Sloshing, Shocks, and Bubbles in the Cool Core Cluster Abell 2052
Abstract
We present results from a very deep (650 ksec) Chandra X-ray observation of Abell 2052, as well as archival VLA radio observations. The data reveal exquisite detail in the inner parts of the cluster, including bubbles evacuated by the AGN's radio lobes, compressed bubble rims, filaments, and loops. Two concentric shocks are seen, and a temperature rise is measured for the innermost one. On larger scales, an excess surface brightness spiral feature is detected. The spiral has cooler temperatures and higher abundances than its surroundings, and is likely the result of sloshing gas initiated by a previous cluster-cluster or sub-cluster merger. Initial evidence for previously unseen bubbles at larger radii related to earlier outbursts from the AGN is presented.
