Porovnání modelů relativistické čáry železa
Svoboda, Jiří ; Dovčiak, Michal ; Goosmann, René ; Karas, Vladimír
The analysis of the broad iron line profile in the X-ray spectra of active galactic nuclei and black hole X-ray binaries allows us to constrain the spin parameter of the black hole. We compare the constraints on the spin value for two X-ray sources, MCG-6-30-15 and GX 339-4, with a broad iron line using present relativistic line models in XSPEC - LAOR and KYRLINE.
Záblesky ze spirálních vln ovlivněné efektem čočkování a časového zpoždění?
Karas, Vladimír ; Dovčiak, Michal ; Eckart, A. ; Meyer, L.
We examine physics of flares from spiral waves by lensing and time-delay amplification.
Změna primárního a reprocesovaného záření v modelu záblesků a skvrn
Dovčiak, Michal ; Karas, Vladimír ; Matt, G. ; Goosmann, René
We study variation of the primary and reprocessed radiation in the flare-spot model.
