XRISM xtend observation 202033010

AWM7_P1

Abstract

AGN feedback regulates gas cooling in galaxy clusters, but the precise role of AGN-driven turbulence remains unclear. We propose three XRISM observations of the cool-core cluster AWM 7 to map its ICM velocity dispersion and directly compare with Perseus Cluster PV studies. Unlike Perseus, AWM 7 shows no signs of active AGN feedback, but shares similar redshift and sloshing signatures. By matching radial and line-of-sight scales, these observations test whether small-scale gas motions found in Perseus arise from AGN feedback. Our goals include measuring turbulence, non-thermal pressure support, chemical abundance profiles, and resonant scattering. AWM 7, as a bright feedback-free cluster, provides a unique opportunity to isolate the kinematic role of AGN feedback in cluster cores.
