An XSPEC model to explore spectral features from black-hole sources - II. The relativistic iron line in the lamp-post geometry
Michal Dovciak, Jiri Svoboda, Rene W. Goosmann +3
In X-ray spectra of several active galactic nuclei and Galactic black hole binaries a broad relativistically smeared iron line is observed. This feature arises by fluorescence when…

Black hole accretion rings revealed by future X-ray spectroscopy
V. Sochora, V. Karas, J. Svoboda +1
Spectral features can arise by reflection of coronal X-rays on a black hole accretion disc. The resulting profile bears various imprints of strong gravitational field acting on the…

Extremal energy shifts of radiation from a ring near a rotating black hole
Vladimir Karas, Vjaceslav Sochora
Radiation from a narrow circular ring shows a characteristic double-horn profile dominated by photons having energy around the maximum or minimum of the allowed range, i.e. near th…
