Hybrid disc geometry for shocked accretion flows: Unveiling QPOs in black hole X-ray binaries
Monu Singh, Sudip Kumar Garain, Santabrata Das
We investigate the efficacy of semi-analytical global accretion solutions in capturing the flow properties observed in two-dimensional numerical simulations of shocked accretion on…
Relativistic Accretion Flow in a Generic Class of Spherically Symmetric Static Spacetime
Pradeepkumar Yadav, Sayan Chakrabarti, Santabrata Das
We investigate the properties of low angular momentum, inviscid, advective accretion flows in a generic static and spherically symmetric spacetime that incorporates higher-order co…
Influence of winds on shocked magnetized viscous accretion flows around rotating black holes
Camelia Jana, Santabrata Das
We study global transonic solution for a relativistic, magnetized, viscous advective accretion flow around a rotating black hole, incorporating the effects of mass and angular mome…
Neutrino-dominated relativistic shocked accretion flow around rotating black hole: implications for short gamma-ray bursts
Amit Kumar, Sayan Chakrabarti, Santabrata Das
We investigate the physical properties of the central engine powering gamma-ray bursts (GRBs), modelled as a stellar-mass black hole accreting via a neutrino-dominated accretion fl…
Dark matter halos and transonic accretion flow
Avijit Chowdhury, Gargi Sen, Sayan Chakrabarti +1
The interplay between supermassive black holes (SMBHs) and their surrounding environment is fundamental to understanding galactic evolution. This work investigates the influence of…
GRMHD modelling of accretion flow around Sagittarius A constrained by EHT measurements
Gargi Sen, Debaprasad Maity, Santabrata Das
We study low angular momentum, advective accretion flows around a Kerr black hole within the framework of general relativistic magnetohydrodynamics (GRMHD) in the steady state. By…
