Abstract | We have been awarded a Large Program in AO13 to measure the mass profiles of acomplete sample of massive galaxy clusters at 0.9< z< 1.15, with a precisionsimilar to that currently obtained for local objects. The primary goal is toassess the evolution of the dark matter concentration at cluster scales, acritical test of theoretical scenario of structure formation. This data set willalso constrain the evolution of fundamental mass-proxy relations and theevolution of the gas entropy and pressure profiles in the high mass regime, atest of gravitational gas heating. We propose to re-observe two targets, theobservation of which was dramatically affected by flares. |

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. |
