Black hole masses from power density spectra: determinations and consequences
B. Czerny, M. Nikolajuk, M. Piasecki +1
We analyze the scaling of the X-ray power density spectra with the mass of the black hole on the example of Cyg X-1 and Seyfert 1 galaxy NGC 5548. We show that the high frequency t…
The UV spectra of NLS1s - Implications for their broad line regions
J. K. Kuraszkiewicz, B. J. Wilkes, B. Czerny +3
We study the UV spectra of NLS1 galaxies and compare them with typical Seyfert 1 galaxies and quasars. The NLS1 spectra show narrower UV lines as well as weaker CIV lambda 1549 and…
Disk/corona model: The transition to ADAF
B. Czerny, A. Rozanska, A. Janiuk +1
We propose a model of the accretion flow onto a black hole consisting of the accretion disk with an accreting two-temperature corona. The model is based on assumptions about the ra…
