Abstract:
The INTEGRAL mission provides a large data set for studying the hard
X-ray properties of AGN and allows testing the unified scheme for AGN.
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.
