An XMM-Newton Study of Hard X-ray Sources
E. Piconcelli, L. Bassani, M. Cappi +3
We briefly report on an on-going spectroscopic study of hard X-ray sources selected serendipitously in 12 XMM-Newton fields. Results for the analysis of the 41 sources from the fir…
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…
Exploring the spectral properties of faint hard X-ray sources with XMM-Newton
E. Piconcelli, M. Cappi, L. Bassani +3
We present a spectroscopic study of 41 hard X-ray sources detected serendipitously with high significance (> 5 sigma in the 2-10 keV band) in seven EPIC performance/verification ph…
XMM-Newton observations of ultraluminous X-ray sources in nearby galaxies
L. Foschini, G. Di Cocco, L. C. Ho +9
An XMM-Newton study of ultraluminous X-ray sources (ULX) has been performed in a sample of 10 nearby Seyfert galaxies. Eighteen ULX have been found with positional uncertainty of a…
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…
