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.
