XRISM observations of Abell 1795 show line-of-sight velocity dispersion falling from 114 km/s in the core to 68 km/s at 320 kpc, near-zero bulk velocities, multiphase gas, and 14% resonant suppression of the Fe XXV w line.

TNG-Cluster simulations find that in galaxy cluster centers turbulence accounts for under half the total velocity dispersion (typically 50-75 km/s), is mostly subsonic, provides sub-percent pressure support, and is primarily driven by SMBH feedback.
XRISM measurements indicate turbulent dissipation from jets struggles to balance cooling in cluster atmospheres except possibly in limited inner regions of systems like Hydra A.
