The X-ray variability properties of PG quasars: XMM-Newton results
M. Guainazzi, E. Jimenez-Bailon, E. Piconcelli
This paper presents preliminary results of a systematic study on the X-ray spectral variability of PG quasars with XMM-Newton. We concentrate on those objects, whose X-ray spectra…

The X-ray properties of the PG QSO sample observed with XMM-Newton
Elena Jimenez-Bailon, Enrico Piconcelli, Matteo Guainazzi +1
We present preliminary results of a systematic analysis of the XMM-Newton spectra of nearby optically-bright QSOs. The objects have been optically selected from the Bright Quasar S…

The starburst-AGN of NGC1808 observed with XMM-Newton
E. Jimenez-Bailon, M. Santos-Lleo, M. Dahlem +3
NGC1808 is a nearby spiral galaxy that harbours an active central region with an extent of 20 arcsec (i.e. 1 kpc). Previous X-ray and optical/NIR observations have provided convinc…
