Study of Unidentified EGRET sources with INTEGRAL: first results and future prospects
G. Di Cocco, A. J. Castro-Tirado, S. Chaty +12
The primary objective of the study of unidentified EGRET sources with INTEGRAL is to locate with a few arcminute accuracy the hard X-ray / soft gamma-ray counterparts within the EG…
Hard X-ray emission from Serpens X-1 as observed by INTEGRAL
N. Masetti, L. Foschini, E. Palazzi +5
We here report results of an INTEGRAL observation of the X-ray burst and atoll source Ser X-1 performed on May 2003. The object was observed for a total of 400 ks but nearly 8 degr…
XMM-Newton Survey of a Distance-limited Sample of Seyfert Galaxies: Preliminary Spectral Results
M. Cappi, G. Di Cocco, F. Panessa +19
An unbiased estimate of the average intrinsic X-ray properties and column density distribution of Seyfert galaxies in the local Universe is crucial to validate unified models of ac…
Search for relativistic beaming in ultraluminous X-ray sources
L. Foschini, G. Malaguti, G. Di Cocco +3
The nature of the ultraluminous X-ray sources (ULX) is still to be understood. Several hypotheses have been suggested to explain the high X-ray luminosity: stellar mass black holes…
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…
