Abstract

Active Galactic Nuclei (AGN) feedback regulates cooling and star formation in galaxy clusters. Its sphere of influence, imprinted on the intracluster medium (ICM), offers key insights into feedback physics and serves as a robust diagnostic for numerical models. We propose three pointings (166 ks total) to map the feedback sphere of influence in the Perseus cluster. This will yield the most detailed ICM kinematic map to date, covering the transition between feedback- and merger-dominated regions. We will investigate azimuthal variations in gas kinematics and metallicity, and address how AGN bubbles and sloshing arms transport and confine energy. Together with multiwavelength data, we will explore if/how AGN-driven turbulence triggers the radio mini-halo and thermal instabilities in the ICM.
