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…
XMM-NEWTON Observation of the Seyfert 2 Galaxy NGC 4138
L. Foschini, F. Panessa, A. L. Longinotti +9
The XMM-Newton data presented here are the first X-ray observation of the Seyfert 2 galaxy NGC4138. Although the galaxy has been pointed by ROSAT-HRI, it was not detected, with a f…
IBIS/PICsIT Data and Analysis
J. B. Stephen, L. Foschini, F. Gianotti +12
The imager IBIS on board INTEGRAL is composed of two detector planes: ISGRI (15 keV - 1 MeV) and PICsIT (170 keV - 10 MeV). Here we describe the data structure of PICsIT and the in…
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…
