The X-ray Coronae of two massive galaxies in the core of the Perseus cluster
N. Arakawa, A. C. Fabian, S. A. Walker
We study the X-ray properties of two elliptical galaxies, NGC 1270 and NGC 1272, in the core of the Perseus cluster with deep Chandra observations. Both galaxies have central super…
Physics of cosmic plasmas from high angular resolution X-ray imaging of galaxy clusters
Maxim Markevitch, Esra Bulbul, Eugene Churazov +15
Galaxy clusters are massive dark matter-dominated systems filled with X-ray emitting, optically thin plasma. Their large size and relative simplicity (at least as astrophysical obj…
The Advanced X-ray Imaging Satellite
Richard F. Mushotzky, James Aird, Amy J. Barger +41
Much of the baryonic matter in the Universe, including the most active and luminous sources, are best studied in the X-ray band. Key advances in X-ray optics and detectors have pav…
What fraction of the density fluctuations in the Perseus cluster core is due to gas sloshing rather than AGN feedback?
S. A. Walker, J. S. Sanders, A. C. Fabian
Deep Chandra observations of the core of the Perseus cluster show a plethora of complex structure. It has been found that when the observed density fluctuations in the intracluster…
The split in the ancient cold front in the Perseus cluster
Stephen A. Walker, John ZuHone, Andy Fabian +1
Sloshing cold fronts in clusters, produced as the dense cluster core moves around in the cluster potential in response to in-falling subgroups, provide a powerful probe of the phys…
Effects of the variability of the nucleus of NGC1275 on X-ray observations of the surrounding intracluster medium
A. C. Fabian, S. A. Walker, C. Pinto +2
The active galaxy NGC1275 lies at the centre of the Perseus cluster of galaxies, which is the X-ray brightest cluster in the Sky. The nucleus shows large variability over the past…
