The relativistic shift of narrow spectral features from black-hole accretion discs
T. Pechacek, M. Dovciak, V. Karas +1
Transient spectral features have been discovered in the X-ray spectra of Active Galactic Nuclei, mostly in the 5--7 keV energy range. Several interpretations were proposed for the…

X-ray Variability of Active Galactic Nuclei and the Flare Model
R. W. Goosmann, B. Czerny, A. -M. Dumont +4
Short-term variability of X-ray spectra has been reported for several Active Galactic Nuclei. Significant X-ray flux variations are observed within time scales down to 10^4 -- 10^5…

Polarization signatures of strong gravity in black-hole accretion discs
V. Karas, M. Dovciak, G. Matt
We discuss the effects of strong gravity on the polarization properties of a black hole accretion disc. The intrinsic polarization is computed taking into account light scattered o…
