Radiative efficiency, variability and Bondi accretion onto massive black holes: from mechanical to quasar feedback in brightest cluster galaxies
H. R. Russell, B. R. McNamara, A. C. Edge +3
We examine unresolved nuclear X-ray sources in 57 brightest cluster galaxies to study the relationship between nuclear X-ray emission and accretion onto supermassive black holes (S…
Herschel observations of extended atomic gas in the core of the Perseus cluster
Rupal Mittal, J. B. Raymond Oonk, Gary J. Ferland +11
We present Herschel observations of the core of the Perseus cluster of galaxies. The brightest cluster galaxy, NGC 1275, is surrounded by a network of filaments previously imaged e…
Shock fronts, electron-ion equilibration and ICM transport processes in the merging cluster Abell 2146
H. R. Russell, B. R. McNamara, J. S. Sanders +8
We present a new 400 ks Chandra X-ray observation of the merging galaxy cluster Abell 2146. This deep observation reveals detailed structure associated with the major merger event…
The X-ray luminous cluster underlying the z = 1.04 quasar PKS1229-021
H. R. Russell, A. C. Fabian, G. B. Taylor +5
We present a 100 ks Chandra observation studying the extended X-ray emission around the powerful z=1.04 quasar PKS1229-021. The diffuse cluster X-ray emission can be traced out to…
