| Abstract | We propose a 45 ksec observation of Abell S1063 (z=0.3475), the second mostX-ray luminous cluster in the ROSAT-ESO Flux Limited X-ray (REFLEX) galaxycluster survey and maybe one of the most massive clusters known. Chandra dataimply strong centroid variation with the core being clearly offset. The veryhigh luminosity L_44=30 and high temperaure T=11 keV imply that this cluster isboosted by merger effects. If this is true for AS1063 we should see a starktemperature structure perhaps similar to that of the bullet clusterRXJ0658-55. It is necessary to produce highly resolved temperature maps tocategorize these clusters and to understand their formation and this is notpossible with the existing Chandra data. |

| 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. |
