On Seyfert spectra and variability
P. Magdziarz
We discuss the observational phenomenology of Seyferts from the point of view of the disk model, and argue that the spectral variability may be related to geometrical changes of th…
Strong gravity and X-ray spectroscopy
A. Maciolek-Niedzwiecki, P. Magdziarz
This paper reviews the effects of general relativity in an X-ray spectrum reflected from a cold matter accreting onto a black hole. The spectrum consists of the iron K line and…
Complex Absorption and Reflection of a Multi-temperature Cyclotron-Bremsstrahlung X-ray Cooling Shock in BY Cam
C. Done, P. Magdziarz
We re-analyse the ASCA and GINGA X-ray data from BY Cam, a slightly asynchronous magnetic accreting white dwarf. The spectra are strongly affected by complex absorption, which we m…
The X-ray spectrum of the polar BY Cam
C. Done, P. Magdziarz
ASCA and GINGA X-ray data from the magnetic Cataclysmic Variable BY Cam show that the spectrum is strongly affected by complex absorption, probably from the pre-shock accretion col…
A model of the broad-band continuum of NGC 5548
P. Magdziarz, O. Blaes
We discuss a model of the central source in Seyfert 1 galaxy NGC 5548. The model assumes a three phase disk structure consisting of a cold outer disk, a hot central disk constituti…
Gamma-ray flux variability in the sample of EGRET blazars
P. Magdziarz, R. Moderski, G. M. Madejski
We analyze average gamma-ray variability statistics for the sample of blazars detected by CGRO/EGRET. We re-reduce all the available EGRET observations and analyze light curves by…
