Multi-wavelength study of a sample of nearby Seyfert galaxies
F. Panessa, L. Bassani, M. Cappi +2
One of the least biased complete Seyfert sample available to date has been considered to perform an X-ray survey using the capabilities of XMM-Newton and Chandra satellites. The X-…
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…
X-ray properties of the "Composite" Seyfert/Star-forming galaxies
A. Wolter, G. Trinchieri, R. Della Ceca +7
An enigmatic, small class of IR and X-ray luminous sources, named ``Composite'' starburst/Seyfert galaxies, has been defined from IRAS and RASS data. The objects have optical spect…
The Faint X-ray Source Population Near the 3C 295 cluster
V. D'Elia, F. Fiore, M. Elvis +5
We present a statistical analysis of the Chandra observation of the source field around the 3C 295 galaxy cluster (z=0.46). Three different methods of analysis, namely a chip by ch…
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…
