Studying X-ray cooling in a luminous cluster with feedback

We propose a 130ks observation of the Xray brightest cluster above z0.1,PKS0745191. In the absence of heating there should be cooling at 1000 Msun/yr.XMM shows the presence of central cool gas and Chandra the location of feedback.We will examine the central temperature distribution with RGS to study thefeedbackcooling connection. In addition, most of r_200 can be studied in asingle pointing to examine clumping. We will examine the surface brightnessfluctuation spectrum as a function of radius to connect to clusterwide andAGNrelated turbulence. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
