The Impact of Plasma Angular Momentum on Magnetically Arrested Flows and Relativistic Jets in Hot Accretion Flows Around Black Holes
Ho-Sang Chan, Prasun Dhang, Jason Dexter +1
In certain scenarios, the accreted angular momentum of plasma onto a black hole could be low; however, how the accretion dynamics depend on the angular momentum content of the plas…
Energy Extraction from a Black Hole by a Strongly Magnetized Thin Accretion Disk
Prasun Dhang, Jason Dexter, Mitchell C. Begelman
The presence of a strong, large-scale magnetic field in an accretion flow leads to extraction of the rotational energy of the black hole (BH) through the Blandford-Znajek (BZ) proc…
Shedding light on the MRI driven dynamo in a stratified shearing box
Prasun Dhang, Abhijit Bendre, Kandaswamy Subramanian
We study the magneto-rotational instability (MRI) driven dynamo in a geometrically thin disc () using stratified zero net flux (ZNF) shearing box simulations. We find tha…
Iterative removal of sources to model the turbulent electromotive force
Abhijit B. Bendre, Jennifer Schober, Prasun Dhang +1
We describe a novel method to compute the components of dynamo tensors from direct magnetohydrodynamic (MHD) simulations. Our method relies upon an extension and generalisation of…
