AGN in XMM-Newton Hard Bright Survey
Listed in IVOA Registry (Virtual Observatory)
We investigate here the X-ray luminosity function (XLF) of absorbed (N_H_ between 4x10^21^ and 10^24^cm^-2^) and unabsorbed (N_H_<4x10^21^cm^-2^) AGN, the fraction of absorbed AGN as a function of L_X_ (and z), the intrinsic N_H_ distribution of the AGN population, and the XLF of Compton thick (N_H>10^24^cm^-2^) AGN.
Description
To carry out this investigation, we have used the XMM-Newton Hard Bright Serendipitous Sample (HBSS), a complete sample of bright X-ray sources (f_x_>~7x10^-14^erg/cm^2^/s) at high galactic latitude (|b|>20{deg}) selected in the 4.5-7.5keV energy band.
The HBSS sample is now almost completely identified (97% spectroscopic identifications) and it can be safely used for a statistical investigation. The HBSS contains 62 AGN out of which 40 are unabsorbed (or marginally absorbed; N_H_<4x10^21^cm^-2^) and 22 are absorbed (N_H_ between 4x10^21^ and ~10^24^cm^-2^).
