In a new study, researchers from Chalmers University of Technology, Sweden, and the University of Louvain, Belgium, evaluated over a thousand policy proposals for how the EU could reduce this impact, to assess which would have the largest potential to reduce deforestation – while also being politically feasible.</b></p><div><span style="background-color:initial">“Unsurprisingly, there is weaker support for tougher regulations, such as import restrictions on certain goods. But our study shows that there is broad support in general, including for certain policies that have real potential to reduce imported deforestation,” says Martin Persson, Associate Professor of Physical Resource Theory at Chalmers University of Technology.​</span></div> <div><br /></div> <div><span style="background-color:initial"></span><a href="/en/departments/see/news/Pages/EU-consumption-plays-major-role-in-tropical-deforestation.aspx">Previous research from Chalmers University of Technology has already shown the EU's great impact in this area​</a>. More than half of tropical deforestation is linked to production of food and animal feed, such as palm oil, soybeans, wood products, cocoa and coffee – goods which the EU imports in vast quantities. The question is, what can the EU do to reduce its contribution to deforestation?</div> <div> </div> <div><br /></div> <div> </div> <div>“This issue is particularly interesting now, as this year the EU is planning to present legislative proposals for reducing deforestation caused by European consumption. The question has been discussed by the EU since 2008, but now something political is actually happening,” says Simon Bager, a doctoral student at the Université Catholique de Louvain, Belgium, and lead author of the study.</div> <div> </div> <div><br /></div> <div> </div> <div>The authors of the article mapped 1141 different proposals, originating from open consultations and workshops, where the EU has collected ideas from companies, interest groups and think tanks. The researchers also compiled proposals from a large number of research reports, policy briefs and other publications, where different stakeholders have put forward various policy proposals. After grouping together similar proposals, they arrived at 86 unique suggestions.</div> <div> </div> <div><br /></div> <div> </div> <h2 class="chalmersElement-H2">Two sugg​estions stand out</h2> <div> </div> <div><span style="background-color:initial">Finding proposals for measures that would have the desired effect but are also possible to implement in practice, and enjoy the necessary political support, is no easy task. But after their extensive survey, the researchers identify two policy options in particular which show promise. The first is to make importers of produce responsible for any deforestation in their supply chains, by requiring them to carry out the requisite due diligence.</span><br /></div> <div> </div> <div><span style="background-color:initial"><br /></span></div> <div> </div> <div>“If the importing companies’ suppliers have products that contribute to deforestation, the company may be held responsible for this. We consider such a system to be credible and possible to implement both politically and practically – there are already examples from France and England where similar systems have been implemented or are in the process thereof,” says Simon Bager.</div> <div> </div> <div>“Due diligence is also the measure which is most common in our survey, put forward by many different types of actors, and there is broad support for this proposal. However, it is important to emphasise that for such a system to have an impact on deforestation, it must be carefully designed, including which companies are affected by the requirements, and which sanctions and liability options exist.”</div> <div> </div> <div><br /></div> <div> </div> <div>The other possibility is to support multi-stakeholder forums, where companies, civil society organisations, and politicians come together to agree on possible measures for ridding a supply-chain, commodity, or area, of deforestation. There are positive examples here too, the most notable being the Amazon Soy Moratorium from 2006, when actors including Greenpeace and the World Wide Fund for Nature gathered with soy producers and exporters and agreed to end soy exports from deforested areas in the Amazon rainforest.</div> <div> </div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/EU-Mercosur-martin-Persson.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />“Examples suc<span style="background-color:initial">h as these demonstrate the effect that multi-stakeholder forums can have. And in our opinion, it is a measure that is easier to get acceptance for, because it is an opportunity for the affected parties to be directly involved in helping design the measures themselves,” says Martin Persson.</span></div> <div> </div> <div><br /></div> <div> </div> <div>Such discussions can also be adapted to the relevant areas or regions, increasing the likelihood of local support for the initiatives.</div> <div> </div> <h2 class="chalmersElement-H2">A delicate ​​balance</h2> <div> </div> <div>The researchers also investigated how to deal with the trade-off between policy impacts and feasibility. An important part of this is combining different complementary measures. Trade regulations on their own, for example, risk hitting poorer producing countries harder, and should therefore be combined with targeted aid to help introduce more sustainable production methods, increasing yields without having to resort to deforestation. This would also reduce the risk of goods that are produced on deforested land simply being sold in markets other than the EU.</div> <div><br /></div> <div> </div> <div>“If the EU now focuses on its contribution to deforestation, the effect may be that what is produced on newly deforested land is sold to other countries, while the EU gets the ‘good’ products. Therefore, our assessment is that the EU should ensure that the measures introduced are combined with those which contribute to an overall transition to sustainable land use in producing countries,” says Simon Bager.</div> <div><br /></div> <div> </div> <div>In conclusion, the researchers summarise three essential principles needed for new measures, if the EU is serious about reducing its impact on tropical deforestation.</div> <div><br /></div> <div> </div> <div>“First, enact measures that actually are able to bring about change. Second, use a range of measures, combining different tools and instruments to contribute to reduced deforestation. Finally, ensure the direct involvement of supply chain actors within particularly important regions, expanding and broadening the measures over time,” concludes Simon Bager.</div> <div><br /></div> <div> </div> <div>The authors hope that the research and identified policy options can serve as inspiration for policy makers, NGOs, industries, and other stakeholders working to address the EU's deforestation footprint. With at least 86 different unique alternatives, there is a wide range of opportunities to focus on the problem – very few of these are political 'non-starters' or proposals which would have no effect on the issue.</div> <div> </div> <div>The full study, Eighty-six EU policy options for reducing imported deforestation is available open-access in the journal One Earth:</div> <div> </div> <div> </div> <div> </div> <h3 class="chalmersElement-H3">For more information, contact:​</h3> <div> </div> <div>Martin Persson, Associate Professor, Physical Resource Theory at Chalmers University of Technology, martin.persson@chalmers.se, +46 31 772 2148</div> <div> </div> <div><br /></div> <div> </div> <div>Simon Bager, Ph.D. candidate UCLouvain and MSCA fellow COUPLED, simon.bager@uclouvain.be, +45 2721 7414</div> <div> </div> <div><br /></div> <div> </div> <div><h3 class="chalmersElement-H3"><span>More detailed information regarding how the study was conducted:</span></h3></div> <div> </div> <div>To investigate the potential impact and political feasibility of the 1141 proposals, the researchers first categorised them based on who submitted the proposal, who the policy would affect, and what type of policy is proposed. Since many of the proposals were essentially the same or similar, they were then summarised, resulting in 86 unique suggestions. The majority are based on weaker measures, such as making more information and types of support available to producers, rather than statutory restrictions and regulations on imports and exports. The researchers interpret this as meaning that there is greater support for softer proposals. However, the researchers themselves consider these proposals to be less effective.</div> <div><br /></div> <div> </div> <div>“One example is eco-labelling, where the purpose is to influence consumers to stop buying products that contribute to deforestation. The intent is good, but previous research does not support the argument that this changes consumer behaviour to such a level that production itself is affected. But if import restrictions are instead introduced on goods that are linked to deforestation, it is already known that this has direct effects,” says Martin Persson.</div> <div><br /></div> <div> </div> <div>After evaluating the likely effects, the next step was to see which proposals could actually receive political support, and how complex and costly the formulation and implementation was likely to be. For this evaluation, methodological innovations were required.</div> <div><br /></div> <div> </div> <div>“After categorising the 1141 proposals, we could see how many stakeholders, and of which kind, proposed a certain type of measure. If the same option was proposed by many actors, of different kinds – environmental organisations, companies, and authorities – we interpreted that as strong, broad support for the proposal,” explains Martin Persson.</div> <div><br /></div> <div> </div> <div>The last two steps in the assessment of the measures were then about how complicated and expensive it would be to realise the proposals.</div> <div><br /></div> <div> </div> <div>“For example, commissioning a research institute to investigate, at a detailed level, what drives deforestation – that would be quite easy. But a new tax or punitive duty at EU-wide level would be very difficult and costly to successfully implement. There are some measures, which the EU can take alone, while others require cooperation with the individual member states or third countries. And there we simply rated the institutional difficulty for implementation of each proposal,” says Simon Bager.</div> <div><br /></div> <div> </div> <div>The last aspect for assessing the political feasibility was looking at the economic impact of the proposal.</div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">“If you influence a large impo</span><span style="background-color:initial">rt flow, that will result in major economic consequences.

The observations with the Event Horizon Telescope (EHT) reveal how energetic jets form close to the black hole, 55 million light years distant. Astronomers from Chalmers are part of the international EHT collaboration.</b></p>​<span style="background-color:initial">The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of a black hole, has revealed a new view of the massive object at the centre of the galaxy Messier 87 (M87): how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of a black hole. The observations are key to explaining how the galaxy, located 55 million light-years away, is able to launch energetic jets from its core.</span><div><br /></div> <div>“We are now seeing the next crucial piece of evidence to understand how magnetic fields behave around black holes, and how activity in this very compact region of space can drive powerful jets that extend far beyond the galaxy,” says Monika Mościbrodzka, Coordinator of the EHT Polarimetry Working Group and Assistant Professor at Radboud University in the Netherlands.</div> <div><br /></div> <div>On 10 April 2019, scientists released the first ever image of a black hole, revealing a bright ring-like structure with a dark central region — the black hole’s shadow. Since then, the EHT collaboration has delved deeper into the data on the supermassive object at the heart of the M87 galaxy collected in 2017. They have discovered that a significant fraction of the light around the M87 black hole is polarised.</div> <div><br /></div> <div>“This work is a major milestone: the polarisation of light carries information that allows us to better understand the physics behind the image we saw in April 2019, which was not possible before,” explains Iván Martí-Vidal, also Coordinator of the EHT Polarimetry Working Group and GenT Distinguished Researcher at the University of Valencia, Spain. He adds that “unveiling this new polarised-light image required years of work due to the complex techniques involved in obtaining and analysing the data.”</div> <div><br /></div> <div>Light becomes polarised when it goes through certain filters, like the lenses of polarised sunglasses, or when it is emitted in hot regions of space where magnetic fields are present. In the same way that polarised sunglasses help us see better by reducing reflections and glare from bright surfaces, astronomers can sharpen their view of the region around the black hole by looking at how the light originating from it is polarised. Specifically, polarisation allows astronomers to map the magnetic field lines present at the inner edge of the black hole. </div> <div><br /></div> <div>“The newly published polarised images are key to understanding how the magnetic field allows the black hole to 'eat' matter and launch powerful jets,” says EHT collaboration member Andrew Chael, a NASA Hubble Fellow at the Princeton Center for Theoretical Science and the Princeton Gravity Initiative in the US.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Centrum/Onsala%20rymdobservatorium/340x/eso2105b_72dpi_340x227.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></div> <div>The bright jets of energy and matter that emerge from M87’s core and extend at least 5000 light-years from its centre are one of the galaxy’s most mysterious and energetic features. Most matter lying close to the edge of a black hole falls in. However, some of the surrounding particles escape moments before capture and are blown far out into space in the form of jets. </div> <div><br /></div> <div><span style="background-color:initial">Astronomers have relied on different models of how matter behaves near the black hole to better understand this process. But they still don’t know exactly how jets larger than the galaxy are launched from its central region, which is comparable in size to the Solar System, nor how exactly matter falls into the black hole. With the new EHT image of the black hole and its shadow in polarised light, astronomers managed for the first time to look into the region just outside the black hole where this interplay between matter flowing in and being ejected out is happening. </span><br /></div> <div><br /></div> <div>The observations provide new information about the structure of the magnetic fields just outside the black hole. The team found that only theoretical models featuring strongly magnetised gas can explain what they are seeing at the event horizon. </div> <div><br /></div> <div>“The observations suggest that the magnetic fields at the black hole’s edge are strong enough to push back on the hot gas and help it resist gravity’s pull. Only the gas that slips through the field can spiral inwards to the event horizon,” explains Jason Dexter, Assistant Professor at the University of Colorado Boulder, US, and Coordinator of the EHT Theory Working Group. </div> <div><br /></div> <div>To observe the heart of the M87 galaxy, the collaboration linked eight telescopes around the world – including the ALMA (Atacama Large Millimeter/submillimeter Array) and APEX (Atacama Pathfinder EXperiment) in northern Chile – to create a virtual Earth-sized telescope, the EHT. The impressive resolution obtained with the EHT is equivalent to that needed to measure the length of a credit card on the surface of the Moon.</div> <div><br /></div> <div>“With ALMA and APEX, which through their southern location enhance the image quality by adding geographical spread to the EHT network, European scientists were able to play a central role in the research,” says Ciska Kemper, European ALMA Programme Scientist at ESO. “With its 66 antennas, ALMA dominates the overall signal collection in polarised light, while APEX has been essential for the calibration of the image.”</div> <div><img src="/SiteCollectionImages/Centrum/Onsala%20rymdobservatorium/340x/eso2105d_72dpi_340x340.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></div> <div><br /></div> <div>&quot;ALMA data were also crucial to calibrate, image and interpret the EHT observations, providing tight constraints on the theoretical models that explain how matter behaves near the black hole event horizon,&quot; adds Ciriaco Goddi, a scientist at Radboud University and Leiden Observatory, the Netherlands, who led an accompanying study that relied only on ALMA observations.</div> <div><br /></div> <div>The EHT setup allowed the team to directly observe the black hole shadow and the ring of light around it, with the new polarised-light image clearly showing that the ring is magnetised.

But that argument is problematic,” says Christian Azar, Professor of Energy and Environment at Chalmers University of Technology. In a filmed keynote presentation at the Act Sustainable Research Conference he questions the &quot;science-demands&quot; rhetoric in a discussion about the relationship between science and politics.</b></p><div><strong>Christian Azar, why is it problematic or even wrong to claim that “the science requires” various actions. </strong></div> <div><span style="background-color:initial">– Science is essentially a method of finding out what the world is like. But what we should do about the various problems humanity faces is a different matter. Science alone cannot give you the answers to that. To find out what we should do about, for example, environmental degradation, we don’t just need knowledge about the problem but also values, and science cannot tell us what those values should be. In essence we can’t say that science requires us to do this or that. </span><br /></div> <div><br /></div> <div><span style="background-color:initial">–</span><span style="background-color:initial"> </span>This difference between facts and values, between what is and what we ought to do, is something we humans have been aware of for centuries. The philosopher David Hume stated already back in the 18th century that we cannot derive an ‘ought’ from an ‘is’. Time after time many people fall back on the idea that science can tell us what we ought to do. It’s a wrong and unfortunate idea. </div> <div><br /></div> <div><strong>But politicians are not experts on the climate, energy technologies, human behaviour, policy instruments and so on, nor can we expect them to be. Shouldn’t the experts decide when the issues are so complex? That’s why we have experts. </strong></div> <div><span style="background-color:initial">–</span><span style="background-color:initial"> </span>Yes, but it’s matter of exercising care. What’s needed is some sort of balance. Experts have to determine how to operate an electrical power grid or a nuclear power plant, and I would obviously rather be operated on by a surgeon than a politician. But when it comes to how much money should be invested in healthcare, the environment or schools, we can’t let experts decide that since these are interests that compete with one another, and it’s a matter of what we value most. These issues are quite central to both the climate issue and the pandemic (where a similar discussion about pitting experts and politicians against one another has emerged). How different goals should be valued against one another is ultimately a political question. We can’t get away from that. </div> <div><strong><br /></strong></div> <div><strong>Why is this important?</strong></div> <div><span style="background-color:initial">–</span><span style="background-color:initial"> </span><span style="background-color:initial">I think there are two reasons for that. </span><span style="background-color:initial">Firstly, it’s a matter of trust. If researchers say that “the science requires” something when that’s not correct, then there’s a risk that we undermine people's trust in science. I believe that that is something we should be careful about because many powerful actors are already trying to feed that mistrust – for instance politicians like Donald Trump – but for completely different reasons. We should simply be careful not to give them legitimate cause for complaint.</span></div> <div> </div> <div><span style="background-color:initial">–</span><span style="background-color:initial"> </span>Secondly, it’s a matter of democracy. If some experts were to decide what we should do in key issues for our society, then we’d be giving up democracy to some extent. This is particularly important in matters such as the climate issue since this is an issue we’ll need to wrestle with for decades to come – and where some actors – scientists, policy makers and environmental movements alike – argue that people have to change large parts or their entire way of life to solve the climate challenge. However, in order to be able to implement major changes over an extended period, it’s necessary for them to have democratic legitimacy. </div> <div><br /></div> <div><strong>What does this mean for the discussion on <a href="https://en.wikipedia.org/wiki/Planetary_boundaries">planetary boundaries​</a> – a key concept in the sustainability debate? They are often presented as boundaries set by science for how much impact we can have on the planet. Researchers such as Johan Rockström, who has been a driving force in the development of these boundaries, say that they are “non-negotiable”. </strong></div> <div><span style="background-color:initial">–</span><span style="background-color:initial"> </span>I think that such formulations are very unfortunate. The goals formulated in their articles may be produced by researchers, but they are also subjective and something reasonable people may disagree about. The more of various pollutants we emit the greater the damage to nature, but the precise level of damage we should accept is a matter of values and not something that science can determine as being correct or not. </div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">–</span><span style="background-color:initial"> </span><span style="background-color:initial">The same applies to risks. There’s a great deal of uncertainty in the climate system, for example. Let’s assume that we believe that extremely serious damage would arise if the temperature were to rise by two degrees, but we are not certain. The damage could also arise below or above two degrees. What level should we then aim for? We’d like to have a certain safety margin against really dire consequences. But how great should that margin be? It depends on how much risk we want to take and that has to do with our values. It’s not something science can determine for us. </span></div> <div><br /></div> <div><span style="background-color:initial">–</span><span style="background-color:initial"> </span>Finally, I’d also like to stress that I don’t think that there is anything wrong with researchers taking part in the public debate. We researchers are also citizens. I also think it’s reasonable for researchers to be involved and suggest targets for various environmental problems – the issues are so complex that experts are needed in the process and it can’t just be left to politics. So there needs to be an interaction between experts in specific areas and politicians – it’s entirely unavoidable. </div> <div><br /></div> <div><span style="background-color:initial">–</span><span style="background-color:initial"> </span>The problem comes when researchers (and others) try to make it appear that their proposals are pure science when they are not. Instead, they should acknowledge that the proposed goals are also based on their values and ethical aspects – and that these values can, of course, also be discussed and questioned. </div> <div><br /></div> <div>In addition to the filmed presentation, you can also read <a href="https://www.dn.se/kultur-noje/christian-azar-misstag-att-lata-vetenskap-ga-fore-politik-i-klimatfragan">Azar’s article about the boundary between politics and science in the newspaper Dagens Nyheter</a> (only available in Swedish though).</div>Wed, 10 Mar 2021 00:00:00 +0100https://www.chalmers.se/en/areas-of-advance/energy/news/Pages/Prestigious-knowledge-prize-awarded-to-Filip-Johnsson.aspxhttps://www.chalmers.se/en/areas-of-advance/energy/news/Pages/Prestigious-knowledge-prize-awarded-to-Filip-Johnsson.aspxPrestigious prize awarded to energy researcher<p><b>​Filip Johnsson, Professor of Sustainable Energy Systems at Chalmers, is the recipient of the Åforsk Foundation&#39;s prestigious Knowledge Award for 2021.

On 12 February, the project ended with a digital event where the students&#39; great scientific results were presented - and where they got to meet Nobel Laureate Reinhard Genzel and Swedish astronaut Christer Fuglesang.</b></p><div><div>The Star Hunt is the tenth edition of Help A Scientist, an annual project where the Nobel Prize Museum connects school classes around the country with researchers at Swedish universities. The students who participated in the Star Hunt have analyzed details in infrared images from space and marked where there may be dust and particles that are about to form new stars. This has been a great help to the Chalmers astronomers , who can spend more time investigating what the dust clouds contain to increase knowledge about how stars are formed.</div></div> <div><br /></div> <div>The three participating astronomers from Chalmers' department of Space, Earth and Environment - Jonathan Tan, Giuliana Cosentino and Rubén Fedriani are all happy with the results and their participation in the project:</div> <div><div>​<br />– I was very impressed by the amount of results we got back from the students. They performed a very meticulous work and was committed during the whole project, says Giuliana Cosentino, Chalmers. </div> <div><br /></div> <div>– I had great expectations for the project, but the level of commitment shown by the students really exceeded them. The interest shown during the school virtual visits, the questions that the students felt comfortable to ask us directly via email, all this gave me a sense of appreciation for my and my colleagues’ work that is by far the greatest results and reward, says Giuliana Cosentino.</div></div> <div><br /></div> <h3 class="chalmersElement-H3">Dark streaks and bright bubbles</h3> <div>The students was given access to a tool called World Wide Telescope, and asked to perform two different tasks. In the first part they were mapping dark streaks, or filaments, and bright structures, &quot;bubbles&quot;, in molecular clouds in different star forming regions. The dark filaments are the birth place of many stars and the idea was to answer how and where these filaments arise, and how the bright bubbles are affecting them. </div> <div>The students mapped 6 000 filaments and 200 bubbles, and contributed greatly to the understanding of these phenomenon. </div> <div><br /></div> <div>In the second task the students were asked to map the stars surrounding massive stars, to test theories about how the massive stars are formed - on their own or if they are influenced by surrounding stars. All in all, 140 000 stars were mapped by the students in the excercise! And the accuracy of their star maps proved to be greater than the previous computerized attempts. </div> <div><br /></div> <div>The astronomers will now follow up, analyze and work on the results, and the plan is to showcase the results in at least one coming research paper. </div> <div><br /></div> <h3 class="chalmersElement-H3">Important to work with school students​</h3> <div><div>– Our research group has a long-standing interest in involving relatively early stage students in research. For example, for the last several years we have been running summer undergraduate research projects at Chalmers. As a result of this work, we were informed about the possibility to work with school students via the Nobel Prize Museum Help a Scientist program - it seemed like an unique and fun opportunity - so we applied, says Jonathan Tan, Chalmers. </div> <div><br /></div> <div>– These students are important to work with, since this is an age when they can be making choices about their future careers. We want to give them some experience of scientific research and hope that some will follow such a career path, says Jonathan Tan.</div> <div><br /></div> <div>The students also sent in 160 poster, describing their results. Among them Jonathan, Giuliana and Rubén chose a winning team from class 8B in Carlssons skola, Stockholm, who will get to come to Chalmers and Onsala Space Observatory, meet the researchers and learn more about their work. </div> <div><br /></div> <div>– I will definitely remember most the interaction with the students. With their passion, curiosity, and fresh ideas, I was motivated to perform my best for them. I will also remember the stimulating teachers that did a great job and the Nobel Prize Museum Staff that worked behind the scenes to run everything smoothly, says Rubén Fedriani, Chalmers. </div> <div><br /></div> <div>– I have learnt many things from this project. Not only from the scientific point of view but also from the pedagogical one. The students have taught me that every single detail is of great importance and that a single sentence can inspire one to pursue a career in astronomy, says Rubén Fedriani, Chalmers.</div></div> <div><br /></div> <div>Text: Christian Löwhagen. </div> <div><br /></div> <div><a href="https://youtu.be/r8d_-1Sz9No?t=2234">Watch the final event of the Star Hunt</a>.

The SKA Observatory (SKAO) will build and operate the world&#39;s largest and most complex radio telescopes to answer big questions about the universe. Chalmers leads Sweden&#39;s participation in the project.</b></p>​<span style="background-color:initial">The new observatory, SKAO, was launched on 4 February 2021 when the first meeting of its governing Council was held. The observatory is the world’s second intergovernmental organisation dedicated to astronomy. </span><div>Catherine Cesarsky has been appointed as the first Chair of the SKAO Council.</div> <div><br /></div> <div>“This is a historic moment for radio astronomy”, she said. “Behind today’s milestone, there are countries that had the vision to get deeply involved because they saw the wider benefits their participation in SKAO could bring to build an ecosystem of science and technology involving fundamental research, computing, engineering, and skills for the next generation, which are essential in a 21st century digital economy.”</div> <div><br /></div> <div>The new observatory has its headquarters at on the grounds of the Jodrell Bank UNESCO World Heritage Site in the United Kingdom, with telescopes located at sites in Australia and South Africa.</div> <div><br /></div> <div>SKAO’s telescope in South Africa will be composed of 197 dish antennas, each 15 m in diameter, located in the Karoo region. Of these, 64 already exist and are operated by the South African Radio Astronomy Observatory (SARAO). The telescope in Australia will be composed of 131 072 two-metre-tall antennas located on the Commonwealth Scientific and Industrial Research Organisation’s (CSIRO) Murchison Radio-astronomy Observatory. </div> <div><br /></div> <div>The creation of SKAO follows a decade of detailed engineering design work, scientific prioritisation, and policy development under the supervision of its predecessor the SKA Organisation, supported by more than 500 engineers, over 1,000 scientists and dozens of policy-makers in more than 20 countries; and is the result of 30 years of thinking and research and development since discussions first took place about developing a next-generation radio telescope.</div> <div><br /></div> <div>Philip Diamond, professor at the University of Manchester, has been appointed as the first Director-General of SKAO.</div> <div><br /></div> <div>“Today marks the birth of a new observatory,” he said. “And not just any observatory – this is one of the mega-science facilities of the 21st century. It is the culmination of many years of work and I wish to congratulate everyone in the SKA community and in our partner governments and institutions who have worked so hard to make this happen. For our community, this is about participating in one of the great scientific adventures of the coming decades. It is about skills, technology, innovation, industrial return, and spin offs but fundamentally it is about a wonderful scientific journey that we are now embarking on.” </div> <div><br /></div> <div>Lars Börjesson, professor of physics at Chalmers, is Sweden’s representative as an observer to the SKAO Council.</div> <div><br /></div> <div>“The establishment of the SKA Observatory is a major event for the field of radio astronomy, and a decisive organisational step towards the construction of the SKA telescope”, he said. “We’ve reached this milestone thanks to a huge amount of work in a truly global network, involving the world’s leading radio astronomy institutes and observatories. Together, across international borders, we have combined expertise and enthusiasm to develop the SKA’s science goals, its technical design and organisational structure, and this is something we can be really proud of. For Sweden, funding has now been secured for participation in the construction phase, and the formal process for membership in the SKA Observatory has been initiated.”</div> <div><br /></div> <div>The first SKAO Council meeting follows the signature of the SKA treaty, formally known as the convention establishing the SKA Observatory, on 12 March 2019 in Rome, and its subsequent ratification by Australia, Italy, the Netherlands, Portugal, South Africa and the United Kingdom and entry into force on 15 January 2021, marking the official birth date of the observatory.</div> <div><br /></div> <div>The council is composed of representatives from the Observatory’s Member States, as well as observer countries aspiring to join SKAO. Sweden is one of several observer countries that took part in the design phase of the SKA, along with Canada, China, France, Germany, India, Spain and Switzerland. These countries’ future accession to SKAO is expected in the coming weeks and months, once their national processes have been completed. Representatives of national bodies in Japan and South Korea complement the select list of observers in the SKAO Council.</div> <div><br /></div> <div>At its first meeting, the SKAO Council approved policies and procedures that have been prepared in recent months – covering governance, funding, programmatic and HR matters, among others. These approvals are required to transfer staff and assets from the SKA Organisation to the observatory.</div> <div><br /></div> <div>“The coming months will keep us very busy, with hopefully new countries formalising their accession to SKAO and the expected key decision of the SKAO Council giving us green light to start the construction of the telescopes,” added Prof. Diamond.</div> <div><br /></div> <div>SKAO will begin recruitment in Australia and South Africa in the next few months, working alongside local partners CSIRO and SARAO to supervise construction, which is expected to last eight years, with early science opportunities starting in the mid 2020s. </div> <div><br /></div> <div><strong>About the SKA Observatory</strong></div> <div><br /></div> <div>SKAO, formally known as the SKA Observatory, is a global collaboration of member states to build and operate cutting-edge radio telescopes to answer fundamental questions about our universe. Headquartered in the UK, its first two telescopes, the two largest and most complex radio telescope networks ever built, will be constructed in Australia and South Africa. A later expansion is envisioned in both countries and other African partner countries. SKAO’s telescopes will conduct transformational science and, together with other state-of-the-art research facilities, address gaps in our understanding of the universe including the formation and evolution of galaxies, fundamental physics in extreme environments and the origins of life. Through the development of innovative technologies and its contribution to addressing global societal challenges, SKAO will play its part to address the United Nations’ Sustainable Development Goals and deliver significant non-science impact across its membership and beyond. </div> <div><br /></div> <div>Current SKAO Members are Australia, Italy, the Netherlands, Portugal, South Africa and the United Kingdom with several other countries, among them Sweden, aspiring to membership or engagement with SKAO in the future.</div> <div><br /></div> <div><strong>About Onsala Space Observatory and Sweden’s role in the SKA project</strong></div> <div><br /></div> <div>Onsala Space Observatory is Sweden's national facility for radio astronomy. The observatory provides researchers with equipment for the study of the earth and the rest of the universe. In Onsala, 45 km south of Gothenburg, it operates four radio telescopes and a station in the international telescope Lofar. The SKA is one of several international projects that the observatory participates in. The observatory is hosted by the Department of Space, Earth and Environment at Chalmers University of Technology, and is operated on behalf of the Swedish Research Council.</div> <div><br /></div> <div>Between 2012 and 2021, Onsala Space Observatory represented Sweden as a member country of the SKA Organization. Chalmers and Onsala Space Observatory have been working on the development of the SKA since its inception. Scientists in Sweden have worked both in preparing the SKA's scientific programme, and developing the technical components and systems that the telescopes need to be able to make new discoveries. Sweden has contributed with the development and prototypes of receivers for SKA's dish antennas, for example unique low-noise amplifiers.</div> <div><br /></div> <div>With the support of Big Science Sweden, Chalmers and Onsala Space Observatory engaged companies in the SKA at an early stage, particularly in areas where Sweden is strong (e.g. radio and microwave engineering, ICT and signal processing), developing close collaborations with several universities and institutes. Thanks to both technical development work and cooperation with other research organizations involved in SKA's development, Sweden has been able to lead the completion and delivery of two important systems for SKA’s telescope in South Africa (about 200 receivers for the frequency band 350 - 1050 MHz, low noise amplifiers for several frequency bands and digitising systems for faint signals). In this work, Sweden works together with colleagues in Canada, France, India, Spain and South Africa.</div> <div><br /></div> <div><strong>Contacts</strong></div> <div><br /></div> <div>Robert Cumming, communicator, Onsala Space Observatory, Chalmers, tel: +46 31-772 5500 or +46 70 493 3114, robert.cumming@chalmers.se.</div> <div>John Conway, professor and director, Onsala Space Observatory, Chalmers, +46 31-772 5500, john.conway@chalmers.se</div> <div><br /></div> <div><em>Images</em></div> <div><br /></div> <div><em>A (top) - </em><span style="background-color:initial"><em>Composite image of the SKA combining all elements in South Africa and Australia.

The researchers believe the system could provide important clues about how planets, including those in the Solar System, form and evolve.</b></p><p>The Swedish research contribution in this study has been significant, with the participation of, among others, Malcolm Fridlund and Carina Persson at Chalmers University of Technology.<br /><span style="background-color:initial"></span></p> <p><br /></p> <div><span style="background-color:initial"><div>The first time the team observed TOI-178, a star some 200 light-years away in the constellation of Sculptor, they thought they had spotted two planets going around it in the same orbit. However, a closer look revealed something entirely different. </div> <div><br /></div> <div>– Through further observations we realised that there were not two planets orbiting the star at roughly the same distance from it, but rather multiple planets in a very special configuration, says Adrien Leleu from the Université de Genève and the University of Bern, Switzerland, who led a new study of the system published today in Astronomy &amp; Astrophysics.</div> <div><br /></div> <div>The new research has revealed that the system boasts six exoplanets and that all but the one closest to the star are locked in a rhythmic dance as they move in their orbits. In other words, they are in resonance. This means that there are patterns that repeat themselves as the planets go around the star, with some planets aligning every few orbits. </div> <div><br /></div> <div>The five outer exoplanets of the TOI-178 system follow a complex chain of resonance, one of the longest yet discovered in a system of planets. The five outer planets in the TOI-178 system follow a 18:9:6:4:3 chain: while the second planet from the star (the first in the resonance chain) completes 18 orbits, the third planet from the star (second in the chain) completes 9 orbits, and so on. </div> <div><br /></div> <div>The six exoplanets found are very close to the star, with orbital periods ranging from 2 to 21 days, which is closer than the the star's so called habitable zone. But the researchers suggest that, by continuing the resonance chain, they might find additional planets that could exist in or very close to this zone. <br /></div> <div><br /></div> <div>– For a planet to be in the habitable zone where liquid water can be found on the surface, the orbital period in this system must be at least 40 days. The fact that the planets around TOI-178 have orbits so extremely close to their star means that any water on their surfaces would boil away, even though the star is cooler than our Sun, says Carina Persson, at the department of Space, Earth and Environment.<br /></div> <div><br /></div> <div><div><span style="background-color:initial">Read the full press release from ESO, European Southern Observatory: </span><span style="background-color:initial"><a href="https://www.eso.org/public/news/eso2102/?lang">Puzzling six-exoplanet system with rhythmic movement challenges theories of how planets form</a>.</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">The study is published in the article: </span><a href="https://www.eso.org/public/archives/releases/sciencepapers/eso2102/eso2102a.pdf"><div style="display:inline !important"><span style="background-color:initial">&quot;</span><span style="background-color:initial">Six transiting planets and a chain of Laplace resonances in</span></div></a></div> <div><a href="https://www.eso.org/public/archives/releases/sciencepapers/eso2102/eso2102a.pdf"><span style="background-color:initial">TOI-178&quot;</span><span style="background-color:initial">, in Astronomy and Astrophysics</span></a><span style="background-color:initial">. </span></div></div></span></div>Wed, 27 Jan 2021 00:00:00 +0100https://www.chalmers.se/en/departments/see/news/Pages/Beautiful-collisions-hubble-shows-6-galaxy-mergers.aspxhttps://www.chalmers.se/en/departments/see/news/Pages/Beautiful-collisions-hubble-shows-6-galaxy-mergers.aspxBeautiful collisions: Hubble shows 6 galaxy mergers<p><b>​To celebrate a new year, the NASA/ESA Hubble Space Telescope has published a montage of six beautiful galaxy mergers. Each of these merging systems was studied as part of the recent HiPEEC survey to investigate the rate of new star formation within such systems. These interactions are a key aspect of galaxy evolution and are among the most spectacular events in the lifetime of a galaxy.</b></p>​<span style="background-color:initial">It is during rare merging events that galaxies undergo dramatic changes in their appearance and in their stellar content. These systems are excellent laboratories to trace the formation of star clusters under extreme physical conditions.</span><div><br /></div> <div>The Milky Way typically forms star clusters with masses that are 10 thousand times the mass of our Sun. This doesn’t compare to the masses of the star clusters forming in colliding galaxies, which can reach millions of times the mass of our Sun.</div> <div><br /></div> <div>These dense stellar systems are also very luminous. Even after the collision, when the resulting galactic system begins to fade into a more quiescent phase, these very massive star clusters will shine throughout their host galaxy, as long-lasting witnesses of past merging events.</div> <div><br /></div> <div>By studying the six galaxy mergers shown here, the Hubble imaging Probe of Extreme Environments and Clusters (HiPEEC) survey has investigated how star clusters are affected during collisions by the rapid changes that drastically increase the rate at which new stars are formed in these galaxies. </div> <div><br /></div> <div><div>– For me the most interesting result was that the two minor merger <span style="background-color:initial">systems (i.e., the collision between one massive galaxy and a less </span><span style="background-color:initial">massive galaxy) in the study have by far the highest cluster formation </span><span style="background-color:initial">efficiencies, says Sabine König, one of two Chalmers astronomers involved in the study. </span></div></div> <div><br /></div> <div>– So the conditions in these two galaxies support that more of the stellar mass in a galaxy is located in stellar clusters, than what can be observed in the other, major mergers of the study (collisions between two galaxies with equal masses). <span style="background-color:initial">One reason for the difference between the cluster formation efficiencies in this study could be that for the two minor mergers we have found that the stellar clusters are not located where the molecular gas is found, </span><span style="background-color:initial">as one would normally expect it to be</span><span style="background-color:initial">.</span></div> <div><span style="background-color:initial"><br /></span></div> <div><div>–That's why I find it particularly important to not only study major <span style="background-color:initial">galaxy mergers and their importance for how galaxies and the Universe </span><span style="background-color:initial">evolve, but indeed the minor mergers as well, which occur much more </span><span style="background-color:initial">often than the major mergers, says Sabine König.</span></div></div> <div><br /></div> <div>Hubble’s capabilities have made it possible to resolve large star-forming “knots” into numerous compact young star clusters. Hubble’s ultraviolet and near-infrared observations of these systems have been used to derive star cluster ages, masses, and extinctions and to analyse the star formation rate within these six merging galaxies. The HiPEEC study reveals that the star cluster populations undergo large and rapid variations in their properties, with the most massive clusters formed towards the end of the merger phase.</div> <div><br /></div> <div>Each of the merging systems shown here has been previously published  by Hubble.</div> <div><br /></div> <div>The text is based on a <a href="https://esahubble.org/news/heic2101/">press release from ESA/NASA: When Galaxies Collide: Hubble Showcases 6 Beautiful Galaxy Mergers​</a>, edited by Christian Löwhagen.</div> <h3 class="chalmersElement-H3">More information</h3> <div><a href="https://esahubble.org/">The Hubble Space Telescope​</a> is a project of international cooperation between NASA<span style="background-color:initial">, National Aeronautics and Space Administration</span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"> and ESA</span><span style="background-color:initial">, the European Space Agency. </span></div> <span></span><div></div> <div><br /></div> <div>The HiPEEC survey was led by Angela Adamo, Stockholm University.

This is stated by researchers in a new report, which also shows that current emission levels of carbon dioxide are incompatible with the climate targets of 1.5 to 2 degrees temperature increase. Filip Johnsson, professor of sustainable energy systems at Chalmers University of Technology, has read the report and comments on it here.</b></p>​<span style="background-color:initial">It has been five years since the Paris Agreement was concluded. The planned extraction of fossil fuels in the world will make the agreement’s global warming goals impossible to meet. A special report, <a href="https://productiongap.org/">The Production Gap​</a>, was launched in December 2020. Researchers from several research institutes together with the UN's environmental program examined how much fossil fuels are planned to be used by 2030 and compared their use with the fossil-fuel reduction required to limit global warming according to climate goals. The gap has grown since last year.<br /><br /></span><div><img src="/sv/styrkeomraden/energi/nyheter/PublishingImages/filipj.jpg" alt="Filip Johnsson" class="chalmersPosition-FloatRight" style="margin:5px" />“The report shows a far too large gap between how much the world's fossil fuel use would need to be reduced and different countries' plans to utilize their fossil fuels. In many cases, plans are being made for the expansion of fossil fuel use, and in many cases fossil fuels are being subsidized. It is important to remember that there are many countries, unlike countries such as Sweden, which have large domestic reserves of fossil fuels and they tend to use their resources. We pointed out that challenge a couple of years ago in Dagens Nyheter: <a href="https://www.dn.se/debatt/ingen-minskning-av-fossil-energi-trots-storsatsning-pa-fornybart/">No reduction in fossil energy despite a major investment in renewables​</a>”, says Filip Johnsson.<br /><br /></div> <div>“The positive thing is that many companies have started to communicate that they intend to become climate neutral at a certain year and that this should include all emissions resulting from their products, including emissions in connection with the extraction of materials and inputs, emissions of production and emissions caused by using the product”, says Filip Johnsson, who hopes that many politicians, business leaders and actors in the financial market will embrace the message in the report.<br /><br /></div> <div><div><strong>The pandemic has been going on for a while</strong>. Is it even possible to change course and meet climate targets now when many industries are fighting for their survival and the government is forced to present crisis package after crisis package?</div> <div>“I think there is a will among many politicians. But much of the measures and the support that has been decided on so far are to eliminate short-term effects on redundancies and unemployment, and then the capacity to act to influence is not so great. But now time has come to plan for a change”.<br /><br /></div> <div><strong>What do you think is the best thing about the report?</strong></div> <div>“That it shows in black and white that it is urgent to change the development. Not least to find ways for the EU and Sweden to establish so-called border adjustments so that carbon intensive products imported from fossil-rich countries are subject to the same carbon dioxide tax as we will have within the EU. There are many indications that it would accelerate the phasing out of fossil fuels in countries such as China and other countries, from which we import much of our consumer goods. It must be “out of fashion” with fossil fuels”.</div></div> <div></div> <div><br /></div> <div><strong>Who should read the report?</strong></div> <div>“It is more like the opposite, who shouldn’t read it?
