Carter-Penrose diagrams for emergent spacetime in axisymmetrically accreting black hole systems
Susovan Maity, Md Arif Shaikh, Pratik Tarafdar +1
For general relativistic, inviscid, axisymmetric flow around Kerr black hole one may choose different flow thickness. The stationary flow equations can be solved using methods of d…

Influence of the geometric configuration of accretion flow on the black hole spin dependence of relativistic acoustic geometry
Pratik Tarafdar, Tapas Kumar Das
Linear perturbation of general relativistic accretion of low angular momentum hydrodynamic fluid onto a Kerr black hole leads to the formation of curved acoustic geometry embedded…
