Hot-spot model for accretion disc variability as random process
T. Pechacek, V. Karas, B. Czerny
Theory of random processes provides an attractive mathematical tool to describe the fluctuating signal from accreting sources, such as active galactic nuclei and Galactic black hol…
Observing the strong gravity regime of accreting black holes with Simbol-X
R. W. Goosmann, M. Dovciak, V. Karas
The X-ray reflection features of irradiated accretion disks around black holes enable us to probe the effects of strong gravity. We investigate to which precision the reflection si…
Variation of the primary and reprocessed radiation in the flare-spot model
M. Dovciak, V. Karas, G. Matt +1
We study light curves and spectra (equivalent widths of the iron line and some other spectral characteristics) which arise by reprocessing on the surface of an accretion disc, foll…
Variation in the primary and reprocessed radiation from an orbiting spot around a black hole
M. Dovciak, V. Karas, G. Matt +1
We study light curves and spectra (equivalent widths of the iron line and some other spectral characteristics) which arise by reflection on the surface of an accretion disc, follow…
FERO (Finding Extreme Relativistic Objects): statistics of relativistic broad Fe K alpha lines in AGN
A. L. Longinotti, I. de La Calle, S. Bianchi +2
The properties of the relativistically broadened Fe K alpha line emitted in Active Galactic Nuclei (AGN) are still debated among the AGN community. Recent works seem to exclude tha…
Constraining global parameters of accreting black holes by modeling magnetic flares
R. W. Goosmann, M. Mouchet, M. Dovciak +3
We present modeling results for the reprocessed radiation expected from magnetic flares above AGN accretion disks. Relativistic corrections for the orbital motion of the flare and…
