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…

Effect of spin on the dynamics of multi-component trans-relativistic accretion flows around Kerr black holes
Kalyanbrata Pal, Souvik Ghose, Shilpa Sarkar +1
We investigate the axially symmetric accretion of low angular momentum hydrodynamic matter onto a rotating black hole. The gravitational field under consideration is assumed to be…

Spherical accretion in the Schwarzschild spacetime in the Newtonian analogous construct
Shubhrangshu Ghosh, Souvik Ghose, Kalyanbrata Pal +2
The velocity-dependent Newtonian analogous potentials (NAPs) corresponding to general relativistic (GR) spacetimes accurately capture most of the relativistic features, including a…
