  Title: TEMPERATURE MEASUREMENT OF A SAMPLE OF DISTANT LUMINOUS ROSAT CLUSTERS OF GALAXIES


Abstract:
 Distant massive clusters of galaxies are key objects for constraining cosmological
 scenarios. In this respect, we have selected 8 rich clusters from the ROSAT
 All-Sky-Survey and undertaken a multi-wavelength campaign which is to bring, for the
 first time, a unique data base of quality comparable to that reached for nearby
 objects. We have already performed high resolution optical and radio observations as
 well as deep ROSAT pointings; the sample will be extensively covered during the ISO
 central programme. We propose to measure the ICM temperature with ASCA, a
 fundamental parameter for characterizing, in close connection with the informations
 from the other WL, the dynamical state of these young objects. ASCA observations of the complete sample is an ESA/ISAS/NASA collaboration.
