Survey of Novel Deep Learning Architectures for Denoising Gravitational-wave Signals
Rohan Raha, Prayush Kumar
Gravitational-wave denoising must handle the full diversity of spinning, precessing binaries, since the recovered waveform underpins parameter estimation, tests of general relativi…
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…
GRMHD Simulations of Magnetized Accretion Disk/Jet: Variabilities of Black Holes and Spectral Energy Distributions in Magnetic States
Rohan Raha, Banibrata Mukhopadhyay, Koushik Chatterjee
We perform three-dimensional general relativistic magnetohydrodynamic (GRMHD) simulations of a near-maximally spinning black hole (spin parameter, a = 0.998) with varying initial m…
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…
GRMHD simulations of black hole accretion variabilities: Implications to hard state X-ray binary transients
Rohan Raha, Banibrata Mukhopadhyay, Koushik Chatterjee
Using high-resolution general relativistic magnetohydrodynamic (GRMHD) simulations, we investigate accretion flows around spinning black holes and identify three distinct accretion…
Magnetically arrested advective accretion flows and jets/outflows around stellar mass black holes: Explaining hard state ULXs with GRMHD simulations
Rohan Raha, Banibrata Mukhopadhyay, Koushik Chatterjee
An optically thin advective accretion disk is crucial for explaining the hard state of black hole sources. Using general relativistic magnetohydrodynamic (GRMHD) simulations, we in…
Euclidean quantum gravity for Kerr-Newman Spacetimes
Rohan Raha
It is very important to calculate the amount of radiation from a black hole as the radiation from a black hole contributes to its entropy. In this paper I have calculated the Entro…
