Abstract: One of the most interesting astrophysical phenomenon is the astrophysical flow near a 3D black hole. In this paper, we have adopted the Hamiltonian approach to investigate the matter accretion onto Einstein-power-Maxwell black hole in… read more here.

Abstract: Accretion is the process by which matter around a compact massive gravitational object or a system flow into its center of mass. In this paper we consider the accretion onto an RN-AdS black hole surrounded… read more here.

Abstract: Accreting supermassive black holes (SMBHs) can exhibit variable emission across the electromagnetic spectrum and over a broad range of timescales. The variability of active galactic nuclei (AGNs) in the ultraviolet and optical is usually at… read more here.

DOI: 10.1088/1475-7516/2017/09/023
Abstract: We obtain an analytic solution for accretion of a gaseous medium with a adiabatic equation of state (P=ρ) onto a Reissner-Nordstrom black hole which moves at a constant velocity through the medium. We obtain the… read more here.

DOI: 10.1103/physrevd.104.123021
Abstract: We consider spherically symmetric accretion onto a small, possibly primordial, black hole residing at the center of a neutron star governed by a cold nuclear equation of state (EOS). We generalize the relativistic Bondi solution… read more here.

DOI: 10.1103/physrevlett.130.115201
Abstract: We study the accretion of collisionless plasma onto a rotating black hole from first principles using axisymmetric general-relativistic particle-in-cell simulations. We carry out a side-by-side comparison of these results to analogous general-relativistic magnetohydrodynamic simulations. Although… read more here.
