Quenching Cluster Cooling Flows with Recurrent Hot Plasma Bubbles
Claudio Dalla Vecchia, Richard Bower, Tom Theuns +3
The observed cooling rate of hot gas in clusters is much lower than that inferred from the gas density profiles. This suggests that the gas is being heated by some source. We use a…
