The split in the ancient cold front in the Perseus cluster

26 Feb 2018 Walker Stephen A. NASA/GSFC ZuHone John CfA Fabian Andy IoA Sanders Jeremy MPE

Sloshing cold fronts in clusters, produced as the dense cluster core moves around in the cluster potential in response to in-falling subgroups, provide a powerful probe of the physics of the intracluster medium (ICM), and the magnetic fields permeating it. These sharp discontinuities in density and temperature rise gradually outwards with age in a characteristic spiral pattern, embedding into the intracluster medium a record of the minor merging activity of clusters: the further from the cluster centre a cold front is, the older it is...
