Probing magnetized accretion disk-jet systems: stellar mass to supermassive black holes
Mayank Pathak, Rohan Raha, Banibrata Mukhopadhyay
Ubiquitous nature of accretion disks and associated jets in modern astrophysics is extreme for black holes. The current state-of-the-art of black hole activities lies with modeling…
Spectral analysis of magnetized advective accretion flows around rotating black holes
Mayank Pathak, Shubhrangshu Ghosh, Banibrata Mukhopadhyay
The spectra of an accretion disk around black holes are the basic diagnostic tool to enlighten the underlying flows and then black holes. Accretion flows around black holes, howeve…
Possible fractal nature of accretion flows in MAD and SANE simulations: Implications to GRS 1915+105
Srishty Aggarwal, Rohan Raha, Mayank Pathak +1
The general relativistic magnetohydrodynamic (GRMHD) simulations are widely used to study accretion disk and jet dynamics around a black hole. Despite strong observational evidence…
Lepton asymmetry leading to baryogenesis by primordial black holes
Mriganka Dutta, Banibrata Mukhopadhyay, Abhishek Kumar Jha +2
Baryogenesis remains an unresolved problem in cosmology, with existing mechanisms facing significant caveats. We show that the effects of primordial black holes (PBHs) on neutrinos…
