Properties of X-ray selected Broad Absorption Line Quasars
A. J. Blustin, T. Dwelly, M. J. Page +6
Broad absorption line quasars (commonly termed BALQSOs) contain the most dramatic examples of AGN-driven winds. The high absorbing columns in these winds, ~10^24 cm^-2, ensure that…
The Contribution of Radio Selected Star Forming Galaxies to the IR Energy Density Budget
N. Seymour, T. Dwelly, D. Moss +6
We have used several different methods (radio morphology, radio spectral index, mid-IR to radio and near-IR to radio flux density ratios) to discriminate between AGN and SFGs in fa…
A deep INTEGRAL hard X-ray survey of the 3C 273/Coma region
S. Paltani, R. Walter, I. M. McHardy +3
(abridged) We present an analysis of the deepest hard X-ray survey to date of about 2500 deg^2 performed by the IBIS instrument on board INTEGRAL in the 20-60 keV band, with a tota…
The Star Formation History of the Universe as Revealed by Deep Radio Observations
N. Seymour, T. Dwelly, D. Moss +6
Discerning the exact nature of the sub-mJy radio population has been historically difficult due to the low luminosity of these sources at most wavelengths. Using deep ground based…
The XMM-SSC survey of hard-spectrum XMM-Newton sources 1: optically bright sources
M. J. Page, I. Lehmann, Th. Boller +15
We present optical and X-ray data for a sample of serendipitous XMM-Newton sources that are selected to have 0.5-2 keV vs 2-4.5 keV X-ray hardness ratios which are harder than the…
A 610 MHz Survey of the 1H XMM-Newton/Chandra Survey Field
D. Moss, N. Seymour, I. M. McHardy +3
We present the results of a deep 610 MHz survey of the 1^H XMM/Chandra survey area with the GMRT. The resulting maps have a resolution of ~7 arcsec and an rms noise limit of 60 mic…
The distribution of absorption in AGN detected in the XMM-Newton observations of the CDFS
T. Dwelly, M. J. Page
We have used very deep XMM-Newton observations of the Chandra Deep Field-South to examine the spectral properties of the faint active galactic nucleus (AGN) population. Crucially,…
X-ray spectra of sources in the 13H XMM-Newton / Chandra deep field
M. J. Page, N. S. Loaring, T. Dwelly +8
We present the X-ray spectra of 86 optically-identified sources in the 13H XMM-Newton/Chandra deep field which have >70 X-ray counts. The sample consists of 50 broad line AGN, 25 n…
Unveiling the distribution of absorption in the AGN population
Tom Dwelly, Mathew J. Page
We use the very deep XMM-Newton observations in the CDF-S to measure the distribution of absorption in the AGN population. We describe the Monte Carlo method used to unveil the int…
XMM-Newton 13H Deep field - I. X-ray sources
N. S. Loaring, T. Dwelly, M. J. Page +10
We present the results of a deep X-ray survey conducted with XMM-Newton, centred on the UK ROSAT 13H deep field area. This region covers 0.18 deg^2 and is the first of two areas co…
Constraints on the distribution of absorption in the X-ray selected AGN population found in the 13H XMM-Newton/Chandra deep field
T. Dwelly, M. J. Page, N. S. Loaring +4
We present an analysis of the X-ray properties of sources detected in the 13H XMM-Newton deep (200ks) field. In order to constrain the absorbed AGN population, we use extensive Mon…
