Reflections of AGN Outbursts in the Hot Gas in Galaxies and Clusters
Astronomers now know that most galaxies harbor a supermassive black hole at their center. At high redshifts, these galaxies experienced a very active phase, when these black holes produced enormous amounts of energy, likely fueled through galaxy mergers. Today, some of these supermassive black holes still undergo occasional outbursts that are seen through spectacular jets, cavities and buoyant bubbles and shocks in the surrounding X-ray gas. In this talk I will review recent Chandra results on AGN outbursts in the rich clusters MS0735.6+7421, Perseus, Hydra A and M87/Virgo as well as the effects of outbursts in Centaurus A and other elliptical galaxies and groups.
