Effects of self-gravity of the accretion disk around rapidly rotating black hole in long GRBs
Ishika Palit, Agnieszka Janiuk, Petra Sukova
We prescribe a method to study the effects of self-gravity of accretion disk around a black hole associated with long Gamma Ray Bursts (GRBs) in an evolving background Kerr metric.…
Time variability of low angular momentum accretion flows around black hole
Ishika Palit, Agnieszka Janiuk, Petra Sukova
We present the relativistic 2D and 3D GRMHD simulation of axisymmetric, inviscid, hydrodynamic accretion flows in a fixed Kerr black hole gravitational field. The flow is having lo…
Mass and spin constraint on black holes in long GRBs
Ishika Palit, Agnieszka Janiuk, Petra Sukova
We compute the evolution of a quasi-spherical, slowly rotating accretion flow around a black hole, whose mass and spin evolve adequately to the mass-energy transfer through the hor…
Effects of adiabatic index on the sonic surface and time variability of low angular momentum accretion flows
Ishika Palit, Agnieszka Janiuk, Petra Sukova
We study the role of adiabatic index in determining the critical points in the transonic low angular momentum accretion flow onto a black hole. We present the general relativistic…
Accretion in a dynamical spacetime and spinning up of the black hole in the gamma ray burst central engine
Agnieszka Janiuk, Petra Sukova, Ishika Palit
We compute the evolution of a quasi-spherical, slowly rotating accretion flow around a black hole, whose mass and spin evolve adequately to the mass-energy transfer through the hor…
Black hole accretion in gamma ray bursts
Agnieszka Janiuk, Michal Bejger, Petra Sukova +1
We study the structure and evolution of the hyperaccreting disks and outflows in the gamma ray bursts central engines. The torus around a stellar mass black hole is composed of fre…
