On the duration of long GRBs: effects of black hole spin
Agnieszka Janiuk, Rafal Moderski, Daniel Proga
In the frame of the collapsar model for long gamma ray bursts (GRBs), we investigate the formation of a torus around a spinning BH and we check what rotational properties a progeni…
An axisymmetric hydrodynamical model for the torus wind in AGN. II: X-ray excited funnel flow
A. Dorodnitsyn, T. Kallman, D. Proga
We have calculated a series of models of outflows from the obscuring torus in active galactic nuclei (AGN). Our modeling assumes that the inner face of a rotationally supported tor…
Nonaxisymmetric Effects in the Black Hole Accretion Inviscid Hydrodynamics: Formation and Evolution of a Tilted Torus
Agnieszka Janiuk, Daniel Proga, Ryuichi Kurosawa
We report on the fourth phase of our study of slightly rotating accretion flows onto black holes. The main new element of this study is that we used fully three dimensional (3-D) n…
An axisymmetric, hydrodynamical model for the torus wind in AGN
A. Dorodnitsyn, T. Kallman, D. Proga
We report on time-dependent axisymmetric simulations of an X-ray excited flow from a parsec-scale, rotating, cold torus around an active galactic nucleus. Our simulations account f…
Time variability of accretion flows: effects of the adiabatic index and gas temperature
Monika Moscibrodzka, Daniel Proga
We report on next phase of our study of rotating accretion flows onto black holes. We consider hydrodynamical (HD) accretion flows with a spherically symmetric density distribution…
