Hitomi measurements of the dynamics of the intracluster medium in the Perseus Cluster
Abstract
The Soft X-ray Spectrometer on Hitomi measured the velocity dispersion of the intracluster medium in the Perseus Cluster with a precision of 10 km/s. The dispersion in the region lying 30-60 kpc from the nucleus is 164 km/s meaning that turbulent energy density is less than 4% of the thermal energy. The implications for the operation of AGN Feedback in the cluster core will be discussed.
