Radio AGN in galaxy clusters: heating hot atmospheres and driving supermassive black hole growth over cosmic time    [PDF]

C. -J. Ma, B. R. McNamara, P. E. J. Nulsen

We estimate the average radio-AGN (mechanical) power deposited into the hot atmospheres of galaxy clusters over more than three quarters of the age of the Universe. Our sample was drawn from eight major X-ray cluster surveys, and includes 685 clusters in the redshift range 0.1View original: http://arxiv.org/abs/1206.7071
