Subsonic accretion of cooling gas in clusters of galaxies.
Abstract
Slow-moving galaxies in the cores of X-ray emitting clusters can accrete large quantities of cooling gas. The accretion flow is most likely to occur in a subsonic fashion, stagnating at some finite radius. These ideas are applied to NGC 1275 in the Perseus cluster, and it is suggested that they explain the soft X-ray enhancement in that region as well as the stationary optical filaments.
