We have been awarded a Large Program in AO4 to study the evolution of clusterstructural and scaling properties, using an unbiased sample of 23 distantclusters (zvirgul 0.5) covering a wide dynamic range in mass (2.5 < kT < 12 keV). Ouraim is to provide new insight into the physics of structure formation, both forthe dark matter and the baryonic components. We propose to re-observe 6 targets,the observations of which are 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.
