A Deep XMM-Newton Look at the Most Powerful Radio Halo Merging Galaxy Cluster MACSJ0717.5+3745
Abstract
We present the latest results from the 150 ks XMM-Newton observation of the most powerful radio halo galaxy cluster MACS J0717.5+3745 (z=0.55). This spectacular merging galaxy cluster reveals important clues into the connection between the population of non-thermal synchrotron emitting particles and the diffuse, X-ray emitting, thermal gas. Utilizing XMM-Newton's excellent collecting area and spatial-resolution, we focus upon the morphology of the thermal properties of the diffuse gas and discuss the presence of a potentially non-thermal X-ray spectral component.
