The rapid evolution of AGN feedback in brightest cluster galaxies: switching from quasar-mode to radio-mode feedback
J. Hlavacek-Larrondo, A. C. Fabian, A. C. Edge +4
We present an analysis of the 2-10 keV X-ray emission associated with the active galactic nuclei (AGNs) in brightest cluster galaxies (BCGs). Our sample consists of 32 BCGs that li…
Galaxy cluster outskirts: a universal entropy profile for relaxed clusters?
S. A. Walker, A. C. Fabian, J. S. Sanders +1
We fit a functional form for a universal ICM entropy profile to the scaled entropy profiles of a catalogue of X-ray galaxy cluster outskirts results, which are all relaxed cool cor…
Large-scale Motions in the Perseus Galaxy Cluster
A. Simionescu, N. Werner, O. Urban +6
By combining large-scale mosaics of ROSAT PSPC, XMM-Newton, and Suzaku X-ray observations, we present evidence for large-scale motions in the intracluster medium of the nearby, X-r…
Residual Cooling and Persistent Star Formation amid AGN Feedback in Abell 2597
G. R. Tremblay, C. P. O'Dea, S. A. Baum +18
New Chandra X-ray and Herschel FIR observations enable a multiwavelength study of active galactic nucleus (AGN) heating and intracluster medium (ICM) cooling in the brightest clust…
Further X-ray observations of the galaxy cluster PKS 0745-191 to the virial radius and beyond
S. A. Walker, A. C. Fabian, J. S. Sanders +1
We use new Suzaku observations of PKS 0745-191 to measure the thermodynamic properties of its ICM out to and beyond r_{200} (reaching 1.25r_{200}) with better accuracy than previou…
X-ray observations of the galaxy cluster Abell 2029 to the virial radius
S. A. Walker, A. C. Fabian, J. S. Sanders +2
We present Suzaku observations of the galaxy cluster Abell 2029, which exploit Suzaku's low particle background to probe the ICM to radii beyond those possible with previous observ…
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…
