The XMM large scale structure survey: optical vs. X-ray classifications of active galactic nuclei and the unified scheme
O. Garcet, P. Gandhi, E. Gosset +25
Our goal is to characterize AGN populations by comparing their X-ray and optical classifications. We present a sample of 99 spectroscopically identified X-ray point sources in the…
The XMM-LSS survey. Survey design and first results
M. Pierre, I. Valtchanov, B. Altieri +36
We have designed a medium deep large area X-ray survey with XMM - the XMM Large Scale Structure survey, XMM-LSS - with the scope of extending the cosmological tests attempted using…
VLT near-infrared spectra of hard serendipitous Chandra sources
P. Gandhi, C. S. Crawford, A. C. Fabian
We present near-infrared long-slit spectra of eight optically-dim X-ray sources obtained with ISAAC on the Very Large Telescope. Six of the sources have hard X-ray emission with a…
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…
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…
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…
