Collapse-accelerated small-scale dynamos in the first stars and galaxies
Muhammed Irshad, Pallavi Bhat
Here, we explore magnetic field amplification by the small-scale dynamo (SSD) during the formation of the first stars and galaxies. Gravitational collapse continuously modifies tur…
Small-scale dynamo saturation across magnetic Prandtl numbers using the EDQNM closure
Muhammed Irshad, Kandaswamy Subramanian, Pallavi Bhat
Small-scale dynamos (SSDs) are believed to be the primary source of magnetic fields in all turbulent astrophysical systems, especially those with weak rotation such as elliptical g…
Spectral Evolution and Current Sheet Analysis as Probes of Reconnection-Mediated Decay in Magnetically Dominated Turbulence
Chandranathan Anandavijayan, Pallavi Bhat
The decay of magnetically dominated turbulence exhibits robust inverse transfer of magnetic energy even in the absence of net magnetic helicity, challenging traditional cascade-bas…
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…
Turbulent dynamos in a collapsing cloud
Muhammed Irshad P, Pallavi Bhat, Kandaswamy Subramanian +1
The amplification of magnetic fields is crucial for understanding the observed magnetization of stars and galaxies. Turbulent dynamo is the primary mechanism responsible for that b…
