Transonic accretion and the analogue gravity in multi-component elliptical galaxies hosting pseudo-Schwarzschild black holes
Ripon Sk, Sangita Chatterjee, Sankhasubhra Nag
Low-angular-momentum, axisymmetric, inviscid accretion flows onto a black hole have been studied using the vertical equilibrium disc model, considering multiple pseudo-Schwarzschil…
On the spin dependence of the emergent gravity phenomena as observed in axially symmetric black hole accretion with spatially varying adiabatic index
Kalyanbrata Pal, Souvik Ghose, Ripon Sk +2
The present work addresses an axisymmetrically accreting black hole system from three perspectives: the astrophysical, the dynamical systems, and the emergent gravity standpoint. S…
Model-Dependent Galactic Environment Effects on Multi-Transonic Accretion and Emergent Acoustic Gravity around Kerr Black Holes
Ripon Sk, Sangita Chatterjee, Sankhasubhra Nag
The hydrodynamics of low angular momentum, multi-transonic, axisymmetric, inviscid accretion flow onto a rotating black hole in presence of a galactic environment has been systemat…
Motion of charged particle in Reissner-Nordstrom spacetime: A Jacobi metric approach
Praloy Das, Ripon Sk, Subir Ghosh
The present work discusses motion of neutral and charged particles in Reissner - Nordstrom spacetime. The constant energy paths are derived in a variational principle framework usi…
