We propose to perform a joint XMM/CHANDRA/VIMOS follow-up program of three EISdistant clusters recently spectroscopically confirmed using FORS to be atz=0.81,0.94 and 1.14. We propose to observe with IFU of VIMOS the core of theseclusters in order to measure their virial mass and study their dynamical state.The XMM/CHANDRA observations will be used to measure the X-ray mass and themorphology of the clusters. This will provide essential information on thephysics of gravitational collapse and the relative settling of the gas andgalaxies in the dark matter potential. Furthermore, the gas entropy in the coreand the Lx-T relation will be compared with predictions of various theoreticalmodels, providing greater insight on the physics that governs the ICM evolution.

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.
