A volume-limited sample of X-ray galaxy groups and clusters - I. Radial entropy and cooling time profiles
Electra Panagoulia, Andy Fabian, Jeremy Sanders
We present the first results of our study of a sample of 101 X-ray galaxy groups and clusters, which is volume-limited in each of three X-ray luminosity bins. The aim of this work…
X-ray emission from the Ultramassive Black Hole candidate NGC1277: implications and speculation on its origin
A. C. Fabian, J. S. Sanders, M. Haehnelt +2
We study the X-ray emission from NGC1277, a galaxy in the core of the Perseus cluster, for which van den Bosch et al. have recently claimed the presence of an UltraMassive Black Ho…
Multiphase Signatures of AGN Feedback in Abell 2597
G. R. Tremblay, C. P. O'Dea, S. A. Baum +18
We present new Chandra X-ray observations of the brightest cluster galaxy (BCG) in the cool core cluster Abell 2597. The data reveal an extensive kpc-scale X-ray cavity network as…
Extreme AGN feedback in the Massive Cluster Survey (MACS): a detailed study of X-ray cavities at z > 0.3
J. Hlavacek-Larrondo, A. C. Fabian, A. C. Edge +4
We present the first statistical study of X-ray cavities in distant clusters of galaxies (z > 0.3). With the aim of providing further insight into how AGN feedback operates at high…
Herschel observations of the Centaurus cluster - the dynamics of cold gas in a cool core
Rupal Mittal, Christopher P. O'Dea, Gary Ferland +15
Brightest cluster galaxies (BCGs) in the cores of galaxy clusters have distinctly different properties from other low redshift massive ellipticals. The majority of the BCGs in cool…
The inverse-Compton ghost HDF 130 and the giant radio galaxy 6C 0905+3955: matching an analytic model for double radio source evolution
Philip Mocz, A. C. Fabian, Katherine M. Blundell +3
We present new GMRT observations of HDF 130, an inverse-Compton (IC) ghost of a giant radio source that is no longer being powered by jets. We compare the properties of HDF 130 wit…
