Generation and effects of primordial magnetic fields during inflation
Ashu Kushwaha
In this thesis, we aim to investigate the mechanisms underlying the genesis of magnetic fields in the Universe and explore their potential in addressing the matter-antimatter asymm…
Fast Radio Bursts signal high-frequency gravitational waves
Ashu Kushwaha, Sunil Malik, S. Shankaranarayanan
There is growing evidence for high-frequency gravitational waves (HFGWs) ranging from MHz to GHz. Several HFGW detectors have been operating for over a decade, and two GHz events h…
Effective field theory of magnetogenesis identify necessary and sufficient conditions
Ashu Kushwaha, Abhishek Naskar, Debottam Nandi +1
At astrophysical and cosmological scales, there is a detectable amount of magnetic field. There are several probable origins for this observed magnetic field, including the possibi…
Helical magnetic fields from Riemann coupling
Ashu Kushwaha, S. Shankaranarayanan
We study the inflationary generation of helical magnetic fields from the Riemann coupling with the electromagnetic field. Most models in the literature introduce non-minimal coupli…
