A new definition of the intermediate group of gamma-ray bursts
I. Horvath, L. G. Balazs, Z. Bagoly +2
Gamma-ray bursts can be divided into three groups ("short", "intermediate", "long") with respect to their durations. This classification is somewhat imprecise, since the subgroup o…
Observations of Selected AGN with H.E.S.S
F. Aharonian et al.
A sample of selected active galactic nuclei (AGN) was observed in 2003 and 2004 with the High Energy Stereoscopic System (H.E.S.S.), an array of imaging atmospheric-Cherenkov teles…
The relativistic shift of narrow spectral features from black-hole accretion discs
T. Pechacek, M. Dovciak, V. Karas +1
Transient spectral features have been discovered in the X-ray spectra of Active Galactic Nuclei, mostly in the 5--7 keV energy range. Several interpretations were proposed for the…
On highly eccentric stellar trajectories interacting with a self-gravitating disc in Sgr A*
L. Subr, V. Karas
We propose that Kozai's phenomenon is responsible for the long-term evolution of stellar orbits near a supermassive black hole. We pursue the idea that this process may be driven b…
