XMM observation of AS1063 comma one of the most luminous clusters known

We propose a 45 ksec observation of Abell S1063 (z0.3475), the second mostXray luminous cluster in the ROSATESO Flux Limited Xray (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_4430 and high temperaure T11 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. clusterRXJ065855. 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. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
