Probing structure formation physics with the evolution of cluster properties

We have been awarded a Large Program in AO4 to study the evolution of clusterstructural and scaling properties, using a large sample of distant clusters (zvirgul0.5) covering a wide dynamic range in mass (2.5 < kT < 12 keV). Our aim is toprovide new insight into the physics of structure formation, both for the darkmatter and the baryonic components. We propose to reobserve 2 targets, theobservations of which are dramatically affected by flares. To complete the kT >5 keV range coverage of our sample, we also propose to observe 3 clusters, forwhich no time was allocated in AO4. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
