The most massive baryonic component of galaxy clusters is the intracluster medium icm a diffuse hot weakly magnetized plasma that is most easily observed in the x ray band. 366366 x ray emission from clusters of galaxies cambridge astrophysics chandra nasas chandra x ray observatory is a telescope specially designed to detect x ray emission from very hot regions of the universe such as exploded stars clusters an explanation of cosmic x ray sources from black holes to galaxy clusters as well as a review of the history of x ray astronomy what x rays are and how . Binstitute of astronomy ioa cambridge university madingley road cambridge cb3 0ha uk abstract we review the x ray spectra of the cores of clusters of galaxies recent high resolu tion x ray spectroscopic observations have demonstrated a severe deficit of emission at the lowest x ray temperatures as compared to that expected from simple radia tive cooling models the same observations . Research in the high energy astrophysics division focuses on astronomical objects and processes that emit and absorb energy as x rays which include planets all types of stars neutron stars supernova remnants supermassive and stellar mass black holes galaxies and galaxy clusters
