The clustering of X-ray and sub-mm sources
O. Almaini
It is becoming clear that luminous extragalactic X-ray and sub-mm sources are essentially distinct populations. Thus, if high redshift sub-mm sources represent massive spheroids in…
The ELAIS Deep X-ray Survey
C. J. Willott, O. Almaini, J. Manners +10
We present initial follow-up results of the ELAIS Deep X-ray Survey which is being undertaken with the Chandra and XMM-Newton Observatories. 235 X-ray sources are detected in our t…
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…
The AGN contribution to deep submillimetre surveys and the far-infrared background
O. Almaini, A. Lawrence, B. J. Boyle
A great deal of interest has been generated recently by the results of deep submillimetre surveys, which in principle allow an unobscured view of dust-enshrouded star formation at…
The discovery of a high redshift type 2 QSO
O. Almaini, B. J. Boyle, R. E. Griffiths +3
We report the discovery of a high redshift, narrow emission-line galaxy identified in the optical follow-up of deep ROSAT fields. The object has a redshift of z=2.35 and its narrow…
