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…

Lattice simulations of axion-U(1) inflation: gravitational waves, magnetic fields, and scalar statistics
Ramkishor Sharma, Axel Brandenburg, Kandaswamy Subramanian +1
We numerically study axion-U(1) inflation, focusing on the regime where the coupling between axions and gauge fields results in significant backreaction from the amplified gauge fi…
