Subject astro-ph
AbstractThis poster is a summary of a paper on the subject (Bayer-Kim et al. 2002) that has been submitted for publication in MNRAS. We present X-ray, H alpha, radio, and optical data, both imaging and spectroscopy, of the cluster RX J0820.9+0752 and its peculiar central cluster galaxy (CCG). We announce the discovery of several isolated off-nuclear patches of blue light with strong line-emssion (total L(H alpha) ~ 10^{42}{ergs}^{-1}) and distinct ionizational and kinematic properties, embedded in a region of H alpha/X-ray emission. We propose and investigate a scenario in which a secondary galaxy also featured in our observations has moved through a cooling wake produced by the CCG, thereby producing the observed clumpy morphology and helping to trigger star-formation within the clumps.
