X-rays and gamma-rays from accretion flows onto black holes in Seyferts and X-ray binaries
Andrzej A. Zdziarski, W. Neil Johnson, Juri Poutanen +2
We review observations and theoretical models of X-ray/gamma-ray spectra of radio-quiet Seyfert galaxies and of Galactic black-hole candidates (in the hard spectral state). The obs…

Green's functions for transmission of X-rays and gamma-rays through cold media
P. Magdziarz, A. A. Zdziarski
Using a Monte Carlo method, we study Compton scattering and absorption of X-rays and gamma-rays in cold media. We consider transmission of X/gamma-rays through a shell of an arbitr…

The nature of the X-ray source in NGC 4151
P. Magdziarz, A. A. Zdziarski
Analysis of broad-band X/-ray spectra of NGC~4151 from contemporaneous observations by {\it GRO}/OSSE, {\it ROSAT}, {\it Ginga} and {\it ASCA}, shows that the data are well mode…
