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 Ultra Luminous Infrared Galaxy MKN 231: New clues from BeppoSAX and XMM-Newton

V. Braito, R. Della Ceca, E. Piconcelli +11

We present BeppoSAX and XMM-Newton observations of MKN 231. These observations and in particular the BeppoSAX PDS data allowed us to unveil, for the first time, the highly absorbed…

Search for ultraluminous X-ray sources in nearby galaxies

L. Foschini, G. Di Cocco, L. C. Ho +9

Little is presently known about the nature of ultraluminous X-ray sources (ULX). Different hypotheses have been proposed to explain their properties: intermediate-mass BHs, Kerr BH…

First Results from a XMM-Newton Survey of a Distance-Limited (D < 22 Mpc) Sample of Seyfert Galaxies. II - The Galactic Serendipitous Sources

L. Foschini, G. Di Cocco, M. Dadina +9

We present preliminary results from a study with XMM-Newton of the galactic serendipitous sources in a sample of 28 nearby Seyfert galaxies (with D < 22 Mpc). We concentrate here o…

First Results from a XMM-Newton Survey of a Distance-Limited (D<22 Mpc) Sample of Seyfert Galaxies: I- the Agns

M. Cappi, G. Di Cocco, F. Panessa +18

We report here preliminary results from a survey of nearby Seyfert galaxies using the EPIC CCDs on board XMM-Newton. The total sample consists of 28 Seyfert galaxies, and constitut…

Spectral properties of faint hard X-ray selected sources

E. Piconcelli, L. Bassani, M. Cappi +3

We present preliminary results from a XMM-Newton spectroscopic survey of hard (2 -10 keV) X-ray sources detected serendipitously in seven EPIC FOVs. All observations were performed…
