X-rays from Clusters of Galaxies
A. C. Fabian, S. W. Allen
The X-ray emission from clusters of galaxies enables them to be used as good cosmological probes and as an example for massive galaxy formation. The gas mass fraction in clusters s…
Cosmological constraints from the X-ray gas mass fraction in relaxed lensing clusters observed with Chandra
S. W. Allen, R. W. Schmidt, A. C. Fabian
We present precise measurements of the X-ray gas mass fraction for a sample of luminous, relatively relaxed clusters of galaxies observed with the Chandra Observatory, for which in…
Deep inside the core of Abell 1795: the Chandra view
S. Ettori, A. C. Fabian, S. W. Allen +1
We present X-ray spatial and spectral analysis of the Chandra data from the central 400 kpc (H0 = 50 km/s/Mpc) of the cluster of galaxies Abell 1795. The plasma temperature rises o…
Chandra observations of RXJ1347.5-1145: the distribution of mass in the most X-ray luminous galaxy cluster known
S. W. Allen, R. W. Schmidt, A. C. Fabian
We present Chandra observations of RXJ1347.5-1145, the most X-ray luminous cluster of galaxies known. We report the discovery of a region of relatively hot, bright X-ray emission,…
The X-ray virial relations for relaxed lensing clusters observed with Chandra
S. W. Allen, R. W. Schmidt, A. C. Fabian
We examine the relations linking mass, X-ray temperature and bolometric luminosity for a sample of luminous, relatively relaxed clusters of galaxies observed with the Chandra Obser…
Chandra observations of the galaxy cluster Abell 1835
R. W. Schmidt, S. W. Allen, A. C. Fabian
We present the analysis of 30 ksec of Chandra observations of the galaxy cluster Abell 1835. Overall, the X-ray image shows a relaxed morphology, although we detect substructure in…
