Reflection in Seyfert Galaxies and the Unified Model of AGN
Claudio Ricci, Roland Walter, Thierry J. -L. Courvoisier +1
We present a deep study of the average hard X-ray spectra of Seyfert galaxies. We analyzed all public INTEGRAL IBIS/ISGRI data available on all the 165 Seyfert galaxies detected at…
Extreme flux states of NGC 4151 observed with INTEGRAL
P. Lubinski, A. A. Zdziarski, R. Walter +5
We present a comprehensive spectral analysis of all INTEGRAL data obtained so far for the X-ray--bright Seyfert galaxy NGC 4151. We also use all contemporaneous data from RXTE, XMM…
Multi-Zone warm and cold clumpy absorbers in 3 Seyfert galaxies
C. Ricci, V. Beckmann, M. Audard +1
We present the first detailed X-ray analysis of three AGN, the Seyfert 1 galaxies UGC 3142 and ESO 140-43, and the Seyfert 2 galaxy ESO 383-18, in order to study the geometry and t…
