MAPPING GAS KINEMATICS IN THE X-RAY BRIGHTEST GALAXY CLUSTER
Feedback from Active Galactic Nuclei (AGN) is crucial for regulating cooling and star formation in galaxy clusters. Gas motions driven by the feedback could be important in heating the gas. We propose a multi-pointing observational program for the Perseus cluster, totaling 500 ks. We will study radial and azimuthal variations of gas kinematics and metallicity within the cluster core, mapping a transition between feedback- and mergers-dominated regions, which is crucial for distinguishing various feedback scenarios and revealing the role of turbulence in AGN feedback. We will probe gas sloshing, motions driven by rising bubbles, and turbulence association with the radio mini halo. These observations will be of legacy value, complementing large multi-wavelength data sets on Perseus.
