Scientific paper

Central galaxies in rich clusters are sites of cluster cooling flows, with large masses of gas cooling through X-ray temperatures. Many of these galaxies host powerful radio sources. Our Chandra image of A2052 and others show strong interactions between X-ray gas and radio plasma. The X-ray gas may confine radio lobes, deflect radio jets, and produce Faraday rotation. The radio lobes may displace and compress the X-ray gas; this may lead to enhanced cooling and star formation. We propose Chandra observations of three bright cooling flows with radio sources to image the interaction region with the radio source, and to determine the physical state of the X-ray gas. We will also derive the overall cooling flow properties, including abundance gradients and excess absorption, if any.
