A low-redshift galaxy cluster X-ray Temperature Function incorporating Suzaku data
Cien Shang, Caleb Scharf
We present the first results of a survey of 14 low redshift galaxy clusters using Suzaku. Although luminous (L_x> 1\times 10^{43} erg s^{-1} (0.1-2.4 keV)), these clusters have no…
X-Ray Detection of an Obscured Active Galactic Nucleus in a z=3.09 Radio-quiet Ly-alpha Nebula
Antara Basu-Zych, Caleb Scharf
We present evidence for a highly obscured X-ray source in one of two giant Ly-alpha emission nebulae in the z=3.09 proto-cluster region SSA22. Neither Ly-alpha nebula is associated…
On Detecting the X-ray Silhouette of a Damped Lyman alpha System
Mark Dijkstra, Zoltan Haiman, Caleb Scharf
We explore the possibility of resolving an image of a damped Lyman alpha (DLA) system in absorption against an extended, diffuse background X-ray source. Typical columns of neutral…
The Chandra Fornax Survey - I: The Cluster Environment
C. A. Scharf, D. R. Zurek, M. Bureau
We present the first results of a deep Chandra survey of the inner 1 degree of the Fornax cluster of galaxies. Ten 50 ksec pointings were obtained in a mosaic centered on the giant…
Extended X-ray emission around 4C 41.17 at z=3.8
C. A. Scharf, I. Smail, R. Ivison +3
We present sensitive, high-resolution, X-ray imaging from Chandra of the high-redshift radio galaxy 4C 41.17 (z=3.8). Our 150-ks Chandra exposure detects strong X-ray emission from…
