Dynamo and Jet interconnections in GRMHD simulations of black hole accretion disks
P. S. Santhiya, Pallavi Bhat, Prayush Kumar +2
We present global 3D GRMHD simulations of black hole (BH) accretion disks designed to investigate how MRI-driven dynamo action regulates jet formation and evolution. Unlike standar…

Understanding large-scale dynamos in unstratified rotating shear flows
Tushar Mondal, Pallavi Bhat, Fatima Ebrahimi +1
We combine simulations with new analyses that overcome previous pitfalls to explicate how nonhelical mean-field dynamos grow and saturate in unstratified, magnetorotationally drive…
