The Relation Between Line Emission and Brightest Cluster Galaxies in Three Exceptional Clusters: Evidence for Gas Cooling from the ICM
S. L. Hamer, A. C. Edge, A. M. Swinbank +5
There is a strong spatial correlation between brightest cluster galaxies (BCGs) and the peak density and cooling rate of the intra-cluster medium (ICM). In this paper we combine in…
Chandra and XMM-Newton X-ray observations of AWM 7 - I: Investigating X-ray surface brightness fluctuations
J. S. Sanders, A. C. Fabian
We investigate the levels of small scale structure in surface brightness images of the core of the X-ray bright cool-core galaxy cluster AWM 7. After subtraction of a model of the…
Relativistic iron K X-ray Reverberation in NGC 4151
A. Zoghbi, A. C. Fabian, C. S. Reynolds +1
Recent X-ray observations have enabled the study of reverberation delays in AGN for the first time. All the detections so far are in sources with a strong soft excess, and the meas…
Probing Relativistic Astrophysics Around SMBHs: The Suzaku AGN Spin Survey
C. S. Reynolds, L. W. Brenneman, A. M. Lohfink +5
In addition to providing vital clues as to the formation and evolution of black holes, the spin of black holes may be an important energy source in the Universe. Over the past coup…
Riding the wake of a merging galaxy cluster
R. E. A. Canning, H. R. Russell, N. A. Hatch +7
Using WHT OASIS integral field unit observations, we report the discovery of a thin plume of ionised gas extending from the brightest cluster galaxy in Abell 2146 to the sub-cluste…
X-ray spectral variability in NGC 3783
R. C. Reis, A. C. Fabian, C. S. Reynolds +6
NGC 3783 was observed for approximately 210ks by Suzaku and in this time showed significant spectral and flux variability at both short (20ks) and long (100ks) time scales. The ful…
