The Simbol-X view of the unresolved X-ray background
A. Comastri, R. Gilli, F. Fiore +3
We will briefly discuss the importance of sensitive X-ray observations above 10 keV for a better understanding of the physical mechanisms associated to the Supermassive Black Hole…
The XMM-Newton bright serendipitous survey. Identification and optical spectral properties
A. Caccianiga, P. Severgnini, R. Della Ceca +12
AIMS: We present the optical classification and redshift of 348 X-ray selected sources from the XMM-Newton Bright Serendipitous Survey (XBS) which contains a total of 400 objects (…
Heavily obscured AGN with BeppoSAX, INTEGRAL, SWIFT, XMM and Chandra: prospects for Simbol-X
R. Della Ceca, P. Severgnini, A. Caccianiga +6
According to the latest versions of synthesis modeling of the Cosmic X-ray Background, Compton Thick AGN should represent ~50% of the total absorbed AGN population. However, despit…
Elusive AGN in the XMM-Newton bright serendipitous survey
A. Caccianiga, P. Severgnini, R. Della Ceca +3
AIMS: We investigate here the nature of all the sources (35 in total) in the XBS survey (which is 86% optically identified) showing an optical spectrum dominated by the light from…
The XMM-SSC survey of hard-spectrum XMM-Newton sources 1: optically bright sources
M. J. Page, I. Lehmann, Th. Boller +15
We present optical and X-ray data for a sample of serendipitous XMM-Newton sources that are selected to have 0.5-2 keV vs 2-4.5 keV X-ray hardness ratios which are harder than the…
The XMM-Newton serendipitous survey IV. The AXIS X-ray source counts and angular clustering
F. J. Carrera, J. Ebrero, S. Mateos +14
AXIS (An XMM-Newton International Survey) is a survey of 36 high Galactic latitude XMM-Newton observations covering 4.8 deg2 and containing 1433 serendipitous X-ray sources detecte…
Searching for absorbed AGN in the 2XMM-Newton pre-release EPIC Serendipitous Source Catalogue
Elisabetta Memola, Alessandro Caccianiga, Filomena Cocchia +7
We aim to test a method of efficiently selecting X-ray obscured AGN in the 2XMM-Newton EPIC Serendipitous Source Catalogue. By means of a strong correlation established using the X…
