A Very Deep Chandra Observation of Abell 2052: Bubbles, Shocks, and
  Sloshing
  We present first results from a very deep (~650 ksec) Chandra X-ray
observation of Abell 2052, as well as archival VLA radio observations. The data
reveal detailed structure 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, we report the first detection of an excess
surface brightness spiral feature. The spiral has cooler temperatures, lower
entropies, 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.
