The Structure of the Violent Merger in PLCKESZ G200.9-28.2

We have discovered an unprecedented radio relic at the periphery of the Planckcluster PLCK200 using the GMRT and the JVLA; its morphology suggests two shocksurfaces, and it is oriented >45 degrees relative to the merger axis, unliketypical relics. Shallow XMM data shows a disturbed Xray morphology and emissionextending to the relic.s outer edge. Exploiting the superior collecting area ofXMM, we will resolve both shocks and discern the poorly understood nature of theparticle acceleration mechanism producing the relic. At the same time, we willidentify surface brightness and temperature structures throughout the elongatedcluster and search for evidence of an ongoing multiple merger, which couldexplain the double arc structure and orientation of the relic. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
