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…

Polarization signatures of strong gravity in AGN accretion discs
M. Dovciak, V. Karas, G. Matt
The effects of strong gravity on the polarization of the Compton reflection from an X-ray illuminated accretion disc are studied. The gravitational field of a rotating black hole i…

Relativistic spectral features from X-ray illuminated spots and the measure of the black hole mass in AGN
M. Dovciak, S. Bianchi, M. Guainazzi +2
Narrow spectral features in the 5--6 keV range were recently discovered in the X-ray spectra of a few active galactic nuclei. We discuss the possibility that these features are due…
