Analog Gravity in Magneto-Viscous Fluids: Enhanced Analog Hawking Temperature in Accretion Disks
Aliv Sahoo, Mayank Pathak, Banibrata Mukhopadhyay
We present a three-dimensional visco-magnetoacoustic framework for analog gravity in magnetohydrodynamic (MHD) flows. While standard fluid dissipation typically breaks the Lorentzi…
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…
Disk-Outflow Symbiosis in GRMHD Simulations: Explaining Hard-State ULXs
Mayank Pathak, Banibrata Mukhopadhyay
Ultraluminous X-ray sources (ULXs) have captivated researchers for decades due to their exceptionally high luminosities and unique spectral characteristics. Some of these sources d…
Probing the quantum speed limit and entanglement in flavor oscillations of neutrino-antineutrino system in curved spacetime
Abhishek Kumar Jha, Mriganka Dutta, Mayank Pathak +2
We consider a spinning primordial black hole (PBH) described by the Kerr metric in Kerr-Schild polar coordinates. We derive an analytical expression for the four-vector gravitation…
Simulating ULXs and blazars as GRMHD accretion flows around a black hole
Mayank Pathak, Banibrata Mukhopadhyay
General relativistic magnetohydrodynamic (GRMHD) simulations have been instrumental in our understanding of high energy astrophysical phenomena over the past two decades. Their rob…
Gravitational Influence on the Quantum Speed Limit in Flavor Oscillations of Neutrino-Antineutrino System
Abhishek Kumar Jha, Banibrata Mukhopadhyay, Mriganka Dutta +2
We investigate the quantum speed limit (QSL) during the time evolution of neutrino-antineutrino system under the influence of the gravitational field of a spinning primordial black…
Accretion Disk-Outflow/Jet and Hard State ULXs
Mayank Pathak, Banibrata Mukhopadhyay
Ultraluminous X-ray sources (ULXs) have been objects of great interest for the past few decades due to their unusually high luminosities and spectral properties. A few of these sou…
