A large fraction (D70%È90%) of the X-rayÈdetected galaxy clusters show centrally concentrated X-ray emission from hot gas. This emission, which constitutes an important energy loss, forces the gas to increase its density, accelerating the emission rate. At the center of the clusters, the characteristic cooling time is shorter than the age of the cluster, and the gas, pushed inward by the hotter intracluster medium, may settle toward the central cluster galaxy (
