First Order Phase Transition Induced Graviton Bremsstrahlung: A Multi Peak Gravitational Wave Signature
Dipendu Bhandari, Rajat Kumar Mandal, Arunansu Sil
Gravitational waves (GWs) from first order phase transitions (FOPTs) are conventionally sourced by bubble collisions, sound waves, and plasma turbulence. We propose a novel microsc…

Probing Right Handed Neutrino assisted Reheating with Gravitational Waves and Leptogenesis
Arghyajit Datta, Shaaban Khalil, Rajat Kumar Mandal +1
We investigate a non-instantaneous reheating period in the early Universe, where the inflaton field decays exclusively to right-handed neutrinos (RHNs). The subsequent decay of the…
