Bondi Flow from Various Perspectives
Souvik Ghose, Tapas K. Das
Realization of the stationary integral solutions of steady state transonic accretion flow in spherical symmetry helps to understand accretion phenomena on various astrophysical obj…
Multi-criticality and related bifurcation in accretion discs around non-rotating black holes -- an analytical study
Arpan Krishna Mitra, Aishee Chakraborty, Pratik Tarafdar +1
Low angular momentum, general relativistic, axially symmetric accretion of hydrodynamic fluid onto Schwarzschild black holes may undergo more than one critical transition. To obtai…
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…
Parameterisation space for Cornell potential in a QCD potential model
Krishna Kingkar Pathak, Satyadeep Bhattacharya, Tapashi Das
We make a critical analysis on the free parameters of the Cornell potential and provide a parameterisation space for the strong coupling constant and the…
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…
