A cloud model of active galactic nuclei: the iron K-alpha line diagnostics
V. Karas, B. Czerny, Z. Abrassart +1
The origin and the profile of the iron K-alpha line from active galactic nuclei is being studied. The model with a quasi-spherical distribution of clouds around a compact galactic…
A code for optically thick and hot photoionized media
A. -M. Dumont, A. Abrassart, S. Collin
We describe a code designed for hot media {(T } a few 10 K), optically thick to Compton scattering. It computes the structure of a plane-parallel slab of gas in thermal an…
X-ray emitting-absorbing media in Seyfert 1 galaxies
M. Mouchet, A. Abrassart, D. Porquet +2
Seyfert galaxies have been shown to exhibit a large variety of features in their X-ray spectra from which the environment of the central engine can be deduced. We focus on the two…
Accretion and Emission Processes in AGN: the UV-X Connection
S. Collin, A. Abrassart, B. Czerny +2
The main characteristics of the average spectrum of radio quiet AGN in the UV and X-ray range are reviewed, and the emission mechanisms are discussed in the framework of accretion…
Toy model of obscurational variability in active galactic nuclei
A. Abrassart, B. Czerny
We propose an explanation of the variability of AGN based on a cloud model of accretion onto a black hole. These clouds, present at a distance of 10-100 Schwarzschild radii, possib…
Obscuration model of Variability in AGN
B. Czerny, A. Abrassart, S. Collin-Souffrin +1
There are strong suggestions that the disk-like accretion flow onto massive black hole in AGN is disrupted in its innermost part (10-100 Rg), possibly due to the radiation pressure…
