The universal "heartbeat" oscillations in black hole systems accross the mass-scale
Qingwen Wu, Bozena Czerny, Mikolaj Grzedzielski +7
The hyperluminous X-ray source (HLX-1, the peak X-ray luminosity ) near the spiral galaxy ESO 243-49 is possibly the best candidate for intermediate ma…
Test of the Formation mechanism of the Broad Line Region in Active Galactic Nuclei
Bozena Czerny, Pu Du, Jian-Min Wang +1
The origin of the Broad Line Region (BLR) in active galaxies remains unknown. It seems to be related to the underlying accretion disk but an efficient mechanism is required to rise…
Multi-phase environment of compact galactic nuclei: the role of the Nuclear Star Cluster
A. Różańska, D. Kunneriath, B. Czerny +2
We study the conditions for the onset of Thermal Instability in the innermost regions of compact galactic nuclei, where the properties of the interstellar environment are governed…
Modified viscosity in accretion disks. Application to Galactic black hole binaries, intermediate mass black holes and AGN
Mikołaj Grzędzielski, Agnieszka Janiuk, Bożena Czerny +1
Black holes (BHs) surrounded by accretion disks are present in the Universe at different scales of masses, from microquasars up to the active galactic nuclei (AGNs). The current pi…
Tracing dark energy with quasars
J. Średzińska, B. Czerny, M. Bilicki +7
The nature of dark energy, driving the accelerated expansion of the Universe, is one of the most important issues in modern astrophysics. In order to understand this phenomenon, we…
The intermediate line region in active galactic nuclei
T. P. Adhikari, A. Różańska, B. Czerny +2
We show that the recently observed suppression of the gap between the broad line region (BLR) and the narrow line region (NLR) in some AGN can be fully explained by an increase of…
