Magnetic Fields in the Universe
Kandaswamy Subramanian
The origin and maintenance of large scale magnetic fields in the Universe is discussed. A popular idea is that cosmic batteries generate seed magnetic fields which were amplified b…
Varying the forcing scale in low Prandtl number dynamos
A. Brandenburg, N. E. L. Haugen, Xiang-Yu Li +1
Small-scale dynamos are expected to operate in all astrophysical fluids that are turbulent and electrically conducting, for example the interstellar medium, stellar interiors, and…
Probing feedback in high- galaxies using extended UV luminosity functions
Saumyadip Samui, Raghunathan Srianand, Kandaswamy Subramanian
We fit the recently updated UV luminosity functions (LF) of high- () galaxies using our semi-analytical models of galaxy formation that take into account various…
The generation of helical magnetic field in a viable scenario of Inflationary Magnetogenesis
Ramkishor Sharma, Kandaswamy Subramanian, T. R. Seshadri
We study the generation of helical magnetic fields in a model of inflationary magnetogenesis which is free from the strong coupling and back-reaction problems. To generate helical…
