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…
LOFT: the Large Observatory For X-ray Timing
M. Feroci, J. W. den Herder, E. Bozzo +245
The LOFT mission concept is one of four candidates selected by ESA for the M3 launch opportunity as Medium Size missions of the Cosmic Vision programme. The launch window is curren…
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…
An XSPEC model to explore spectral features from black-hole sources
M. Dovciak, V. Karas, A. Martocchia +2
We report on a new general relativistic computational model enhancing, in various respects, the capability of presently available tools for fitting spectra of X-ray sources. The ne…
