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…

Biased galaxy formation in the fields of high-redshift AGN
J. A. Stevens, M. J. Page, F. J. Carrera +2
We discuss preliminary results from our programme to map the fields of high-redshift AGN. In the context of the hierarchical models such fields are predicted to contain an over-den…

X-ray absorbed QSOs and the QSO evolutionary sequence
M. J. Page, F. J. Carrera, J. Ebrero +2
Unexpected in the AGN unified scheme, there exists a population of broad-line z~2 QSOs which have heavily absorbed X-ray spectra. These objects constitute 10% of the population at…
