| Abstract | We propose to observe a large unbiased sample of distant (z=0.4-0.6) galaxyclusters. The clusters in the sample cover the wide dynamic range in mass (kT=2.5-12 keV) necessary to fully assess the evolution of cluster scaling andstructural properties. This will provide unique insight into the physics ofstructure formation, both for the dark matter and the baryonic components (e.g.how non-gravitational processes drive departures from the predictions of thesimplest self-similar model of gravitational collapse). The project is definedso to make maximum use of XMM and Chandra existing observations. We propose thatthe observations are conducted as a Public Large project. |

| 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. |
