Chandra observations of X-ray source overdensities in distant galaxy cluster fields
N. Cappelluti, M. Cappi, M. Dadina +4
The first systematic study of the serendipitous X-ray source density around 10 high z (0.24<z<1.2) clusters performed with Chandra is presented. A factor \~2 overdensity has been f…
INTEGRAL monitoring of the Black Hole candidate 1E 1740.7-2942
M. Del Santo, A. Bazzano, D. M. Smith +24
The brightest persistent Galactic black hole candidate close to the Galactic Centre, 1E 1740.7-2942, has long been observed with INTEGRAL. In this paper, we report on the long-term…
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…
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 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…
