Transonic accretion flow in the mini discs of a binary black hole system
Subhankar Patra, Bibhas Ranjan Majhi, Santabrata Das
We study the general relativistic transonic accretion flow around the primary black hole, which forms the circumprimary disc (CPD), within a binary black hole (BBH) system. The BBH…

Effect of dark matter halo on transonic accretion flow around a galactic black hole
Subhankar Patra, Bibhas Ranjan Majhi
We investigate the transonic accretion flow in the spacetime of a supermassive black hole (BH) coupled to an anisotropic dark matter fluid, as proposed by Cardoso {\it et al}. We e…

General relativistic viscous accretion flow around Konoplya-Zhidenko black hole
Subhankar Patra, Bibhas Ranjan Majhi, Santabrata Das
We investigate the properties of accretion flows around the Konoplya-Zhidenko (KZ) black hole, which is proposed by deforming the Kerr metric with a single deformation parameter to…
