Scientific paper

We propose Chandra observations of 2 bright cooling core clusters (A2063 & AWM4) with central radio sources. We will image the interaction region with the radio source, and to determine the physical state of the X-ray gas. Previous Chandra images (e.g., A2052) show radio bubbles, with X-ray holes at the radio lobes surrounded by bright X-ray rims. Our short ACIS-I image of A2063, one of our targets, already shows evidence for holes. 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 trigger star formation. We will determine the energetics of the radio source and the possible contribution of radio heating to balance X-ray cooling. We will also derive the overall cooling core properties.
