Mapping the hot baryons in the Universe from XMM-Newton to Athena
Abstract
Most of the hot baryons in the Universe are in the form of a hot and diffuse plasma filling the space between galaxies in clusters and groups of galaxies, the so-called intracluster medium. The temperature of the intracluster medium peaks at 2-15 keV, making clusters and groups of galaxies among the most X-ray luminous objects in the Universe. XMM-Newton with its wide field of view, large effective area, and high resolutions have revealed vital information about the structure formation and enrichment processes recorded in the intracluster medium. I will summarize the highlights of XMM-Newton observations of clusters and groups of galaxies over the past 20 years and present the prospects with Athena.
