The XMM-Newton/2dF survey VII. Is there any X-ray absorption in optically selected QSOs?
A. Akylas, A. Georgakakis, I. Georgantopoulos
We explore the X-ray properties of optically selected QSOs spectroscopically identified in the course of the 2dF QSO survey (2QZ). Our main goal is to expand to higher redshifts pr…

The XMM-Newton/2dF survey IV. The X-ray spectral properties of the hard sources
I. Georgantopoulos, A. Georgakakis, A. Akylas +4
We present an analysis of the X-ray spectral properties of 61 hard X-ray selected (2-8 keV) sources from the bright ( \funits) {\it XMM-Newton}/2dF survey. Th…
