On the detectability of distant Compton-thick obscured quasars
A. C. Fabian, R. J. Wilman, C. S. Crawford
Chandra and XMM-Newton have resolved the 2-8 keV X-ray Background (XRB) into point sources. Many of the fainter sources are obscured active galactic nuclei (AGN) with column densit…
Multi-wavelength observations of serendipitous Chandra X-ray sources in the field of A2390
C. S. Crawford, P. Gandhi, A. C. Fabian +4
We present optical spectra and near-infrared imaging of a sample of serendipitous X-ray sources detected in the field of Chandra observations of the A2390 cluster of galaxies. The…
Detecting high redshift evolved galaxies as the hosts of optically faint hard X-ray sources
L. L. Cowie, A. J. Barger, M. W. Bautz +8
We combine deep Subaru near-infrared images of the massive lensing clusters A2390 and A370 with Keck optical data to map the spectral energy distributions (SEDs) of Chandra X-ray s…
Hot dust in two hard Chandra X-ray sources
R. J. Wilman, A. C. Fabian, P. Gandhi
The two brightest hard X-ray sources discovered serendipitously by Chandra in the field of the lensing cluster A2390 are found to have ISOCAM counterparts at 6.7 and 15 micron. We…
Chandra constraints on the thermal conduction in the intracluster plasma of A2142
S. Ettori, A. C. Fabian
In this Letter, we use the recent Chandra observation of A2142 reported by Markevitch et al. to put constraints on thermal conduction in the intracluster plasma. We show that the o…
Infrared observations of serendipitous hard Chandra X-ray sources
C. S. Crawford, A. C. Fabian, P. Gandhi +2
We present observations of a sample of optically-faint, hard X-ray sources of the kind likely to be responsible for much of the hard X-ray background. We confirm that such sources…
