The majority of galaxies in the Universe, including our own, are found within groups. The study of groups and their galaxies is a special interest of the group at Birmingham. We carry out multiwavelength observations of the group galaxies, X-ray observations of the hot intergalactic gas and radio observations of AGN activity which is found at the centres of some groups. This observational work is linked to cosmological simulations of group formation and evolution, allowing a direct comparison with the theory of cosmic structure formation.

Galaxy groups are especially interesting because:

Galaxy groups can be very diverse in their properties, and we have a number of projects studying groups from a variety of angles. This includes:
