Broad Iron Lines in Active Galactic Nuclei
Reynolds, C. S.; Kendziorra, E.; Wilmsn, J.
The Fe Kα lines seen in many Active Galactic Nuclei (AGN) are thought to originate close to the central supermassive black hole. In this review we summarize the physics of the fluorescent line formation and show that Fe Kα line profile observations can be used to probe relativistic effects in the vicinity of the black hole, concentrating on recent…
Multifrequency study of the very slow nova V723 Cas
Chochol, D.; Vittone, A. A.; Pribulla, T.
Multifrequency behaviour of the very slow nova V723 Cas is reviewed. The long-term photometry of the object revealed the orbital period 0.693265 days of the binary, quasi-periodic oscillations in the envelope of the burst white dwarf and 182 days periodicity of activity due to the mass transfer bursts from the red to the white dwarf probably cause…
