Scientific paper

In many elliptical galaxies, including those at the centers of clusters, Chandra observations show the impact of AGN outbursts on the surrounding hot gas. These outbursts, which can be associated with nuclear jets, create X-ray cavities in the core. Observations of M87in the Virgo cluster also show rings of enhanced emission that are probably shock fronts, similar to those seen in the Perseus cluster. For galaxies in less dense environments, the impact of AGN outbursts also can be dramatic. This talk will present recent Chandra observations of the active galaxies M87 and Centaurus A, as well as results for "normal" ellipticals.
