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…

Gravity as emergent phenomena for spherically symmetric black hole accretion of multi-component flow with relativistic equation of state
Tuhin Paul, Aishee Chakraborty, Souvik Ghose +1
We investigate analogue gravity phenomena arising as a result of the linear perturbation of the spherically symmetric accretion flows onto non rotating black holes, where the gravi…
