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…
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…
Efficient quasi-kinematic large-scale dynamo as the small-scale dynamo saturates
Pallavi Bhat, Kandaswamy Subramanian, Axel Brandenburg
Large-scale magnetic fields in stars and galaxies are thought to arise by mean-field dynamo action due to the combined influence of both helical turbulence and shear. Those systems…
Faraday rotation signatures of fluctuation dynamos in young galaxies
Sharanya Sur, Pallavi Bhat, Kandaswamy Subramanian
Observations of Faraday rotation through high-redshift galaxies have revealed that they host coherent magnetic fields that are of comparable strengths to those observed in nearby g…
A unified large/small-scale dynamo in helical turbulence
Pallavi Bhat, Kandaswamy Subramanian, Axel Brandenburg
We use high resolution direct numerical simulations (DNS) to show that helical turbulence can generate significant large-scale fields even in the presence of strong small-scale dyn…
