XRISM OBSERVATIONS OF THE PERSEUS CLUSTER
We propose a large observational program of the Perseus Cluster - the X-ray brightest nearby galaxy cluster. The program is designed to address several key science questions, including the physics of AGN feedback, gas motions that are driven by AGN feedback and mergers with infalling subclusters, the role of turbulence in particle acceleration, metallicity of the hot gas and search for rare elements, search for charge exchange and 3.5 keV line. The cluster is uniquely suitable to address these questions with reasonable exposure time and with an unparalleled degree of systematic robustness.
