Description We have been awarded a Large Program in AO13 to measure the mass profiles of a complete sample of massive galaxy clusters at 0.9< z< 1.15, with a precision similar to that currently obtained for local objects. The primary goal is to assess the evolution of the dark matter concentration at cluster scales, a critical test of theoretical scenario of structure formation. This data set will also constrain the evolution of fundamental mass-proxy relations and the evolution of the gas entropy and pressure profiles in the high mass regime, a test of gravitational gas heating. We propose to re-observe two targets, the observation of which was dramatically affected by flares.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
