Mass content & dynamical state of 3 optically selected high z openParz>0.8closePar clusters

We propose to perform a joint XMM/CHANDRA/VIMOS followup program of three EISdistant clusters recently spectroscopically confirmed using FORS to be atz0.81,0.94 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 Xray 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 LxT relation will be compared with predictions of various theoreticalmodels, providing greater insight on the physics that governs the ICM evolution. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
