Dynamical analogue spacetimes in non-relativistic flows
Karan Fernandes, Susovan Maity, Tapas K. Das
Analogue gravity models describe linear fluctuations of fluids as a massless scalar field propagating on stationary acoustic spacetimes constructed from the background flow. In thi…
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 flow thickness on general relativistic low angular momentum accretion around spinning black holes
Pratik Tarafdar, Susovan Maity, Tapas K. Das
General relativistic, axisymmetric flow of low angular momentum accretion around a Kerr black hole can have certain geometric configuration where the flow is maintained in hydrosta…
Emergent gravity through non-linear perturbation
Karan Fernandes, Susovan Maity, Tapas K. Das
As of now, all analogue gravity models available in the literature deal with the emergence of an acoustic geometry through linear perturbations of transonic fluids only. It has nev…
Dependence of acoustic surface gravity on disc thickness for accreting astrophysical black holes
Susovan Maity, Pratik Tarafdar, Md. Arif Shaikh +1
For axially symmetric accretion maintained in hydrostatic equilibrium along the vertical direction, we investigate how the characteristic features of the embedded acoustic geometry…
Effective sound speed in relativistic accretion discs around rotating black holes
Susovan Maity, Md Arif Shaikh, Tapas Kumar Das
For axially symmetric accretion maintained in the hydrostatic equilibrium along the vertical direction in the Kerr metric, the radial Mach number does not become unity at the criti…
Effective sound speed in relativistic accretion discs around Schwarzschild black holes
Md Arif Shaikh, Susovan Maity, Sankhasubhra Nag +1
For low angular momentum axially symmetric accretion flow maintained in hydrostatic equilibrium along the vertical direction, the value of the Mach number at the critical points de…
