AGN Feedback in Clusters of Galaxies

Elizabeth Blanton, Boston University

Observations during the last ten years with Chandra have shed much light on the cooling gas in the centers of clusters of galaxies and the role of AGN heating. Cooling of the hot intracluster medium in cluster centers can feed the supermassive black holes found in the cores of the dominant cluster galaxies leading to AGN outbursts which can reheat the gas, stopping cooling and large amounts of star formation. AGN heating can come in the form of shocks, buoyantly rising bubbles that have been inflated by radio lobes, and sound wave propogation. I will review the great progress in this field that has been enabled by the study of Chandra data over the last decade.
