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…
Evidence for profile changes in PSR J1713+0747 using the uGMRT
Jaikhomba Singha, Mayuresh P Surnis, Bhal Chandra Joshi +29
PSR J1713+0747 is one of the most precisely timed pulsars in the international pulsar timing array experiment. This pulsar showed an abrupt profile shape change between April 16, 2…
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…
