متن کاملThe Second INTEGRAL AGN Catalogue
Aims. The INTEGRAL mission provides a large data set for studying the hard X-ray properties of AGN and allows to test the unified scheme for AGN. Methods. We present analysis of INTEGRAL IBIS/ISGRI, JEM-X, and OMC data for 199 AGN that have been reported to be detected by INTEGRAL above 20 keV. Results. The data analysed here allow a significant spectral extraction on 148 objects and optical va...
