Starburst activity in a ROSAT Narrow Emission-Line Galaxy
K. F. Gunn, I. M. McHardy, O. Almaini +12
We present multiwaveband photometric and optical spectropolarimetric observations of the R=15.9 narrow emission line galaxy R117_A which lies on the edge of the error circle of the…
Stellar contributors to the hard X-ray background?
Priyamvada Natarajan, Omar Almaini
We use simple energetic arguments to estimate the contribution of massive X-ray binaries and supernova remnants to the cosmic X-ray background (XRB) at energies in excess of 2 keV.…
X-ray absorption and rapid variability of the dwarf Seyfert nucleus of NGC4395
K. Iwasawa, A. C. Fabian, O. Almaini +4
We report the detection of an absorbed central X-ray source and its strong, rapid variability in NGC4395, the least luminous Seyfert nucleus known. The X-ray source exhibits a numb…
The European Large Area ISO Survey I: Goals, Definition and Observation
Seb Oliver, the ELAIS consortium
We describe the European Large Area ISO Survey (ELAIS). ELAIS was the largest single Open Time project conducted by ISO, mapping an area of 12 square degrees at 15mu with ISO-CAM a…
A deep ROSAT survey XV. the average QSO spectrum and its evolution
A. J. Blair, G. C. Stewart, I. Georgantopoulos +4
Using a sample of 165 X-ray selected QSOs from seven deep ROSAT fields we investigate the X-ray spectral properties of an ``average''radio-quiet broad line QSO as a function of red…
The X-ray/submillimetre link
O. Almaini
It is widely believed that most of the cosmic X-ray background (XRB) is produced by a vast, hitherto undetected population of obscured AGN. Deep X-ray surveys with Chandra and XMM…
