Emergent gravity from Michel flow with position dependent adiabatic index
Apashanka Das, Souvik Ghose, Tapas K. Das
Spherically symmetric, general relativistic Bondi accretion is known as the Michel flow. The stationary integral transonic solutions for the Michel flow has been constructed for mu…
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…
Multiple accretion events as a trigger for Sgr A* activity
Bozena Czerny, Devaky Kunneriath, Vladimir Karas +1
Gas clouds are present in the Galactic centre, where they orbit around the supermassive black hole. Collisions between these clumps reduce their angular momentum, and as a result s…
