Iron lines from transient and persisting hot spots on AGN accretion disks
R. W. Goosmann, M. Mouchet, B. Czerny +4
[abridged] We model the X-ray reprocessing from a strong co-rotating flare above an accretion disk in active galactic nuclei. We explore the horizontal structure and evolution of t…
Response of the warm absorber cloud to a variable nuclear flux in active galactic nuclei
L. Chevallier, B. Czerny, A. Rozanska +1
Recent modeling of the warm absorber in active galactic nuclei has proved the usefulness of constant total (gas plus radiation) pressure models, which are highly stratified in temp…
Magnetic flares in Active Galactic Nuclei: Modeling the iron Kalpha-line
R. W. Goosmann, B. Czerny, M. Mouchet +5
The X-ray spectra of Active Galactic Nuclei (AGN) are complex and vary rapidly in time as seen in recent observations. Magnetic flares above the accretion disk can account for the…
The structure and X-ray radiation spectra of illuminated accretion disks in AGN. III. Modeling fractional variability
R. W. Goosmann, B. Czerny, M. Mouchet +5
[abridged] Extending the work of Czerny et al. (2004), we model the fractional variability amplitude due to distributions of hot spots co-orbiting on the accretion disk around a su…
A new model for the Warm Absorber in NGC 3783: a single medium in total pressure equilibrium
A. C. Goncalves, S. Collin, A. -M. Dumont +4
(Abridged) Many active galactic nuclei exhibit X-ray features typical of the highly ionized gas called "Warm Absorber" (WA). Such a material appears to be stratified, displaying zo…
Modeling the Warm Absorber in AGN
A. Rozanska, R. Goosmann, A. -M. Dumont +1
We present a wide grid of models for the structure and transmission properties of warm absorbers in active galactic nuclei (AGN). Contrary to commonly used constant density models,…
