Using the largest, international
telescopes such as the Atacama Large Millimeter/submillimeter Array (ALMA), we
are investigating the formation and evolution of galaxies during the first few
billion years after the big bang. This epoch represents the rise and peak of
cosmic star formation and black hole growth activity. Major discoveries include finding vast
amounts of gas in galaxies.
Clusters of galaxies are the largest
self-gravitating structures in the Universe. Through a combination of
observations and modelling, we study them both as complex astrophysical systems
and cosmological probes.
We also study cosmic magnetic fields through observations of the polarization properties of radio sources, in particular through measurements of the Faraday rotation which provides information on magneto-ionic media in the foreground of radio galaxies.
