J/A+A/505/417       Second INTEGRAL AGN catalogue            (Beckmann+, 2009)

The second INTEGRAL AGN catalogue. Beckmann V., Soldi S., Ricci C., Alfonso-Garzon J., Courvoisier T.J.-L., Domingo A., Gehrels N., Lubinski P., Mas-Hesse J.M., Zdziarski A.A. <Astron. Astrophys. 505, 417 (2009)> =2009A&A...505..417B

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 20keV. The data analysed here allow a significant spectral extraction on 148 objects and optical variability study of 57 AGN. The slopes of the hard X-ray spectra of Seyfert 1 and Seyfert 2 galaxies are found to be consistent within the uncertainties, whereas lower luminosities are measured for the more absorbed/type 2 AGN. The intermediate Seyfert 1.5 objects exhibit hard X-ray spectra consistent with those of Seyfert 1. When applying a Compton reflection model, the underlying continua appear still the same in Seyfert 1 and 2 with photon index 2, and the reflection strength is about R=1, when assuming different inclination angles. A significant correlation is found between the hard X-ray and optical luminosity and the mass of the central black hole in the sense that the more luminous objects appear to be more massive. There is also a general trend for the absorbed sources and type 2 AGN to have lower Eddington ratios. The black hole mass appears to form a fundamental plane together with the optical and X-ray luminosity of the form LV being proportional to LX0.6.M0.2, similar to that found between radio luminosity LR, LX, and M. The unified model for Seyfert galaxies seems to hold, showing in hard X-rays that the central engine is the same in Seyfert 1 and 2 but seen under different inclination angles and absorption. Description: A catalog of 199 IBIS/ISGRI detected AGN is presented. For those 148 objects significantly detected in the data set analysed here, spectral parameters, fluxes, and luminosities are given, and for objects with more complex spectra the results of a fit to a cut-off power law model are presented. In addition, average properties of the various Seyfert types are given as they are measured for the INTEGRAL AGN. A photometric table of OMC measurements in the V-band is given for 57 AGN.
