Left: Bulk velocity (v_bulk) map of the intracluster medium in the core of the X-ray brightest galaxy cluster, the Perseus cluster, with respect to the redshift z = 0.017284 (heliocentric correction applied) in units of km/s. Right: Line-of-sight velocity dispersion (σ_v) of the intracluster medium in units of km/s. The Chandra X-ray contours are overlaid.
