Spectacular X-ray tails, intracluster star formation and ULXs in A3627
M. Sun, M. Donahue, E. Roediger +5
We present the discovery of spectacular double X-ray tails associated with ESO137-001 and a possibly heated X-ray tail associated with ESO137-002, both late-type galaxies in the cl…
Cavities and shocks in the galaxy group HCG 62 as revealed by Chandra, XMM and GMRT data
Myriam Gitti, Ewan O'Sullivan, Simona Giacintucci +4
We report on the results of an analysis of Chandra, XMM-Newton and new GMRT data of the X-ray bright compact group of galaxies HCG 62, which is one of the few groups known to posse…
Long Term Monitoring of the Dynamics and Particle Acceleration of Knots in the Jet of Centaurus A
J. L. Goodger, M. J. Hardcastle, J. H. Croston +16
We present new and archival multi-frequency radio and X-ray data for Centaurus A obtained over almost 20 years at the VLA and with Chandra, with which we measure the X-ray and radi…
What is a Cool-Core Cluster? A Detailed Analysis of the Cores of the X-ray Flux-Limited HIFLUGCS Cluster Sample
Daniel S. Hudson, Rupal Mittal, Thomas H. Reiprich +3
We use the largest complete sample of 64 galaxy clusters (HIghest X-ray FLUx Galaxy Cluster Sample) with available high-quality X-ray data from Chandra, and apply 16 cool-core diag…
AGN Feedback in the Compact Group of Galaxies HCG 62 - as revealed by Chandra, XMM and GMRT data
M. Gitti, E. O'Sullivan, S. Giacintucci +4
As a part of an ongoing study of a sample of galaxy groups showing evidence for AGN/hot gas interaction, we report on the preliminary results of an analysis of new XMM and GMRT dat…
A High Fidelity Sample of Cold Front Clusters from the Chandra Archive
Matt S. Owers, Paul E. J. Nulsen, Warrick J. Couch +1
This paper presents a sample of "cold front" clusters selected from the Chandra archive. The clusters are selected based purely on the existence of surface brightness edges in thei…
Radio Mode Outbursts in Giant Elliptical Galaxies
Paul Nulsen, Christine Jones, William Forman +4
Outbursts from active galactic nuclei (AGN) affect the hot atmospheres of isolated giant elliptical galaxies (gE's), as well as those in groups and clusters of galaxies. Chandra ob…
The Detectability of AGN Cavities in Cooling-Flow Clusters
L. Birzan, D. A. Rafferty, B. R. McNamara +2
Chandra X-ray Observatory has revealed X-ray cavities in many nearby cooling flow clusters. The cavities trace feedback from the central active galactic nulceus (AGN) on the intrac…
Direct Evidence for Outflow of Metal-enriched Gas Along the Radio Jets of Hydra A
C. C. Kirkpatrick, M. Gitti, K. W. Cavagnolo +4
Using deep Chandra observations of the Hydra A galaxy cluster, we examine the metallicity structure near the central galaxy and along its powerful radio source. We show that the me…
Spitzer Mid-Infrared Spectra of Cool-Core Galaxy Clusters
G. E. de Messières, R. W. O'Connell, B. R. McNamara +4
We have obtained mid-infrared spectra of nine cool-core galaxy clusters with the Infrared Spectrograph aboard the Spitzer Space Telescope. X-ray, ultraviolet and optical observatio…
Cosmic Feedback from Supermassive Black Holes
A. Fabian, E. Churazov, M. Donahue +16
An extraordinary recent development in astrophysics was the discovery of the fossil relationship between central black hole mass and the stellar mass of galactic bulges. The physic…
The Jet-Heated X-ray Filament in the Centaurus A Northern Middle Radio Lobe
R. P. Kraft, W. R. Forman, M. J. Hardcastle +6
We present results from a 40 ks {\em XMM-Newton} observation of the X-ray filament coincident with the southeast edge of the Centaurus A Northern Middle Radio Lobe (NML). We find t…
A Chandra X-ray Analysis of Abell 1664: Cooling, Feedback and Star Formation in the Central Cluster Galaxy
C. C. Kirkpatrick, B. R. McNamara, D. A. Rafferty +6
The brightest cluster galaxy (BCG) in the Abell 1664 cluster is unusually blue and is forming stars at a rate of ~ 23 M_{\sun} yr^{-1}. The BCG is located within 5 kpc of the X-ray…
The Evolution of Galaxy Clusters Across Cosmic Time
M. Arnaud, H. Bohringer, C. Jones +40
The large scale structure of the present Universe is determined by the growth of dark matter density fluctuations and by the dynamical action of dark energy and dark matter. While…
Diffuse baryonic matter beyond 2020
M. Markevitch, F. Nicastro, P. Nulsen +10
The hot, diffuse gas that fills the largest overdense structures in the Universe -- clusters of galaxies and a web of giant filaments connecting them -- provides us with tools to a…
High-energy particle acceleration at the radio-lobe shock of Centaurus A
J. H. Croston, R. P. Kraft, M. J. Hardcastle +19
We present new results on the shock around the southwest radio lobe of Centaurus A using data from the Chandra Very Large Programme observations. The X-ray spectrum of the emission…
