Scientific paper

Central galaxies in rich clusters are the sites of cluster cooling cores, with large masses of gas cooling through part of the X-ray band. Many of these galaxies host powerful radio sources. These sources can displace and compress the X-ray gas leading to enhanced cooling and star formation. We request a re-observation due to background flares of Abell 2063, a bright cooling core. Our Chandra observation showed radio "holes" in the X-ray emission. We will constrain the source of additional pressure in the radio source needed to support overlying shells of X-ray gas. We will address the problem of the lack of kT less than 1-2 keV gas in cooling flows by searching for abundance inhomogeneities, heating from the radio source, and excess absorption.
