The unresolved hard X-ray background: the missing source population implied by the Chandra and XMM-Newton deep fields
M. A. Worsley, A. C. Fabian, F. E. Bauer +6
We extend our earlier work on X-ray source stacking in the deep XMM-Newton observation of the Lockman Hole, to the 2 Ms Chandra Deep Field North and the 1 Ms Chandra Deep Field Sou…
Sub-mm detection of a high redshift Type 2 QSO
V. Mainieri, D. Rigopoulou, I. Lehmann +6
We report on the first SCUBA detection of a Type 2 QSO at z=3.660 in the Chandra Deep Field South. This source is X-ray absorbed, shows only narrow emission lines in the optical sp…
Integral field spectroscopy of the ultraluminous X-ray source Holmberg II X-1
I. Lehmann, T. Becker, S. Fabrika +10
We present optical integral field observations of the H II region containing the ultraluminous X-ray source Holmberg II X-1. We confirm the existence of an X-ray ionized nebula as…
Photometric Redshift of X-Ray Sources in the Chandra Deep Field South
W. Zheng, V. J. Mikles, V. Mainieri +10
Based on the photometry of 10 near-UV, optical, and near-infrared bands of the Chandra Deep Field South, we estimate the photometric redshifts for 342 X-ray sources, which constitu…
The (un)resolved X-ray background in the Lockman Hole
M. A. Worsley, A. C. Fabian, X. Barcons +3
Most of the soft and a growing fraction of the harder X-ray background has been resolved into emission from point sources, yet the resolved fraction above 7 keV has only been poorl…
