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…
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…
Lagrangian Description of Accreting Black Hole Systems in the Context of Emergent Spacetime
Satadal Datta, Tapas K. Das
We make use of the Lagrangian description of fluid motion to highlight certain features in the context of spacetime geometry as emergent phenomena in fluid systems. By using Lagran…
Second Order Perturbative Effects on the Acoustic Geometry
Nandan Roy, Shivani Singh, Sankhasubhra Nag +1
In this work, we have studied the effect of higher order perturbations, particularly the second order in details, on the sonic horizon. We have considered two different schemes of…
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…
Relativistic sonic geometry for isothermal accretion in the Schwarzschild metric
Md Arif Shaikh, Ivleena Firdousi, Tapas K. Das
In this work, we perform linear perturbation on general relativistic isothermal accretion onto a non-rotating astrophysical black hole to study the salient features of the correspo…
