Description We propose to perform a joint XMM-CHANDRA-VIMOS follow-up program of three EIS distant clusters recently spectroscopically confirmed using FORS to be at z=0.81,0.94 and 1.14. We propose to observe with IFU of VIMOS the core of these clusters 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 the morphology of the clusters. This will provide essential information on the physics of gravitational collapse and the relative settling of the gas and galaxies in the dark matter potential. Furthermore, the gas entropy in the core and the Lx-T relation will be compared with predictions of various theoretical models, providing greater insight on the physics that governs the ICM evolution.

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.
