Fortunately there exist complex molecules inside the obscuring material, making it possible to estimate movements, temperatures and densities through molecular spectroscopy. One of the molecules that is used to trace dense gas is HCN, also known as hydrogen cyanide. As a triatomic molecule, HCN can both rotate and vibrate, giving rise to a unique spectrum. Aalto et al. (2015) suggest that HCN in its first vibrational state (HCN-VIB) is an excellent tracer of deeply buried nuclei, and that it also may trace a period of rapid growth of the central SMBH just before the onset of strong feedback.<br /><br />The aim of this work was to explore if there exists a correlation between the ratio of HCN-VIB line luminosity and the far infrared luminosity (L(HCN-VIB)/L(FIR)), and molecular outflows or inflows in (Ultra) luminous infrared galaxies ((U)LIRG:s). This was done by collecting observational data of the HCN-VIB line from the literature and comparing it to OH-velocities observed by Veilleux et al. (2013). Receiving so far unpublished HCN-VIB and HCN data for the galaxy UGC~5101, the vibrational temperature and mass was also estimated as a case study. <br /><br /> Physics Colloquium: Many-body localization, entanglement and natural orbitals<p>PJ lecture room, Origo building 4th floor, Fysikgården 2</p><p>​Colloquium by Jens Bardarson, Assistant Professor, Royal Institute of Technology (KTH), Stockholm</p><h2 class="chalmersElement-H2">​Abstract of talk</h2> <div>In this talk I will discuss the basic notions of many-body localization - the interacting version of Anderson localization - with emphasis on entanglement properties and occupations of natural orbitals (eigenvalues and functions of the one particle density matrix). Both aspects are most readily understood in a picture of emergent integrability, where the effective many-body localized Hamiltonian is described in terms of quasiparticles that are electron-hole dressed version of the noninteracting Anderson orbitals. This picture has a structure which is very similar to that of the Landau fermi liquid theory, and analogy that is both useful and intriguing, and will be discussed in some detail. </div>,-University-of-Colorado.aspx,-University-of-Colorado.aspxGPS Can't Do That, Can It?<p>Seminar room, Onsala Space Observatory</p><p>Kristin Larson, University of Colorado</p><div><br /></div> <div>How building a GPS seismometer led to the development of GPS snow, soil moisture, vegetation and water level sensors​.<br /><br /></div>,-Lund-Observatory.aspx,-Lund-Observatory.aspxNils Ryde, Lund Observatory<p>Seminar room, Onsala Space Observatory</p><p>​Title​: TBA</p>​​Abstract: TBA​ Physics Colloquium: Integrable systems in quantum optics<p>PJ Lecture Hall, Chalmers</p><p>​Colloquium by Daniel Braak, University of Augsburg, Germany.</p> 23rd EVGA, 2017<p></p><p>​The 23rd Working Meeting of the European VLBI Group for Geodesy and Astrometry (EVGA) will be organised at Chalmers University of Technology in Gothenburg 15 - 19 May, 2017.</p>​The meeting will be combined with the inauguration of the new Twin Telescopes at Onsala Space Observatory on 18 May.<br /><br /><strong>Schedule of events:</strong><br />Sun 14 May, 18–20: Icebreaker and registration, Chalmers Conference Center, Entrance to Palmstedssalen<br />Mon 15 May, 09–18: Conference Day-1, Palmstedtssalen<br />Tue 16 May, 09–17: Conference Day-2, Palmstedtssalen<br />Tue 16 May, 19–22: Conference Dinner, place TBD<br />Wed 17 May, 09–17: IVS Analysis Workshop and Splinter Meetings, rooms TBD<br />Thu 18 May, 10–17: Onsala Twin Telescopes inauguration, Onsala Space Observatory<br />Fri 19 May, 09–17: IVS Directing Board Meeting (closed), room TBD<br /><br />For more information please visit the conference webpage: <a href="/en/conference/EVGA2017"></a>,-KTH.aspx,-KTH.aspxJosefin Larsson, KTH<p>Seminar room, Onsala Space Observatory</p><p>Title:TBA</p>​​Abstract: TBA​,-2017.aspx,-2017.aspxSWI Science Consortium meeting, 2017<p>TBA</p><p>​An SWI Science Consortium Meeting will take place at Chalmers University of Technology, Göteborg, Sweden (Campus Johanneberg) on 22-23 May, 2017.</p>​The meeting is scheduled to begin at 9.00 on May 22 and end by 14.00 May 23. <br /><br />For more information please go to <a href="/en/conference/SWI2017" title="Link to the conference web page">English conference web page.</a><br /><br /> Galaxies at Low Frequencies: Processes and Probes<p>Chalmers Johanneberg and Onsala Space Observatory</p><p>​​This workshop will be held in Sweden on May 29 - 2 June in Gothenburg at Chalmers University of Technology, and at Onsala Space Observatory, located about 40 km south of Gothenburg.</p>The aim of the workshop is to bring together members of the LOFAR (Low Frequency Array) Nearby Galaxies Working Groups (in the Magnetism and the Surveys Key Science Projects) and other scientists interested in low-frequency probes of physical processes in nearby galaxies. The topics will include: <br />1) Science: review of and work on ongoing LOFAR projects; probing the thermal and non-thermal gas in galaxies through low-frequency spectral energy distributions; diffusion and ageing of cosmic ray electrons; mapping star formation and evolution in nearby galaxies;  galactic structures (disks, jets, halos); galactic magnetic fields; polarization and depolarization at low frequencies;<br />2) Data: data processing, calibration, polarization.<br />3) Future work: pointed observations and exploitation of the LOFAR surveys, scientific collaborations, preparing for the SKA.<br />Invited speakers: George Heald (Perth; TBC), Volker Heesen (Hamburg), Ann Mao (Bonn), David Mulcahy (Manchester).<br />Registration is possible until 20 April, 2017.<br /><br />For more information and to register got to the <a href="/en/conference/LOFARGalaxies2017" title="Link to the conference webpage" target="_blank">conference webpage.</a><br /> Physics Colloquium: Higgs precision physics as a probe of new dynamics<p>PJ lecture room, Origo building 4th floor, Fysikgården 2</p><p>​Colloquium by Roberto Contino, Scuola Normale Superiore, Pisa, Italy.</p>​<span><span style="display:inline-block"></span></span>,-SRON.aspx,-SRON.aspxRens Waters, SRON<p>Seminar room, Onsala Space Observatory</p><p>​Titel: TBA</p>​<span style="background-color:initial">Abstract: TBA</span><p class="MsoNormal"></p>
