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…

Universal Radial Scaling of Large-Scale Black Hole Accretion for Magnetically Arrested And Rocking Accretion Disks
Aretaios Lalakos, Alexander Tchekhovskoy, Elias R. Most +3
Accretion onto supermassive black holes (BHs) can launch relativistic jets that inject energy and momentum into their surroundings. Understanding how such feedback shapes large-sca…

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…
