THE RADIO/X-RAY CONNECTION IN ABELL 2029

Abstract

Abstract We present results of an analysis of the central regions of Abell 2029 and discuss the connections between the radio and X-ray components of the cluster. Despite the very relaxed appearance of the thermal gas in the outer cluster regions, the Chandra observations reveal significant structure in the cluster core. There are a number of bright X-ray filaments as well as a spiral "excess". Several of the filaments appear to be connected to the steep-spectrum cluster-center radio source PKS 1508+059. An analysis of the temperature structure in the cluster shows that the southern extension of PKS 1508+059 is surrounded by cool X-ray gas, while the northern lobe apparently lies in a region of average temperature. We also discuss the inner regions of the radio source which show two oppositelydirected, collimated jets that disrupt as the jets apparently encounter a drop in the confining thermal plasma
