Abstract


Recent X-ray observations have been showing that the old vision ofclusters as peacefully relaxed structures is in most cases absolutelywrong. Coupled with optical and radio observations, these X-ray datashow evidence for violent mechanisms. Results based on XMM-Newton gastemperature maps for four clusters will be presented here.
