X-ray Spectroscopy of Cooling Clusters
J. R. Peterson, A. C. Fabian
We review the X-ray spectra of the cores of clusters of galaxies. Recent high resolution X-ray spectroscopic observations have demonstrated a severe deficit of emission at the lowe…
XMM observations of the high-redshift quasar RXJ1028.6-0844 at z=4.276: soft X-ray spectral flattening
W. Yuan, A. C. Fabian, A. Celotti +2
We present results from a new XMM-Newton observation of the high-redshift quasar RXJ1028.6-0844 at a redshift of 4.276. The soft X-ray spectral flattening, as reported by a study w…
A Chandra observation of the disturbed cluster core of Abell 2204
J. S. Sanders, A. C. Fabian, G. B. Taylor
We present results from an observation of the luminous cluster of galaxies Abell 2204 using the Chandra X-ray Observatory. We show the core of the cluster has a complex morphologic…
High redshift quasars and the supermassive black hole mass budget: constraints on quasar formation models
J. M. Bromley, R. S. Somerville, A. C. Fabian
We investigate the constraints on models of supermassive black hole (SMBH) and quasar formation obtainable from two recent observational developments: the discovery of luminous qua…
An X-ray absorption analysis of the high-velocity system in NGC 1275
K. Gillmon, J. S. Sanders, A. C. Fabian
We present an X-ray absorption analysis of the high-velocity system (HVS) in NGC 1275 using results from a deep 200 ks Chandra observation. We are able to describe the morphology o…
Extended X-ray emission in the high redshift quasar GB 1508+5714 at z=4.3
W. Yuan, A. C. Fabian, A. Celotti +1
We report the discovery of extended X-ray emission around the powerful high-redshift quasar GB 1508+5714 at z=4.3, revealed in a long Chandra ACIS observation. The emission feature…
