Exploring cosmological gravitational wave backgrounds through the synergy of LISA and ET
Alisha Marriott-Best, Debika Chowdhury, Anish Ghoshal +1
The gravitational wave (GW) interferometers LISA and ET are expected to be functional in the next decade(s), possibly around the same time. They will operate over different frequen…

Inflationary magnetogenesis beyond slow-roll and its induced gravitational waves
Bill Atkins, Debika Chowdhury, Alisha Marriott-Best +1
The origin of magnetic fields observed on both astrophysical and cosmological scales is a compelling problem that has the potential to shed light on the early Universe. We analytic…

Cross-correlation between the curvature perturbations and magnetic fields in pure ultra slow roll inflation
Sagarika Tripathy, Debika Chowdhury, H. V. Ragavendra +1
Motivated by the aim of producing significant number of primordial black holes, over the past few years, there has been a considerable interest in examining models of inflation inv…
