| Abstract | 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 X-ray morphology and emissionextending to the relics 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. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
