High Energy Neutrinos, Gravitational Waves, and Dark Matter from a Cosmological First Order Phase Transition
James M. Cline, Savas Stoica, Yong Xu
We investigate high energy neutrinos (HEs) from the decay of superheavy dark matter (DM) produced during a cosmological first order phase transition. Adopting the filtered DM pr…
Irreducible Graviton Floor from Reheating
James M. Cline, Yong Xu
Inflaton decay inevitably emits gravitons through bremsstrahlung during reheating. We show that the soft part of this emission amplitude, fixed by Weinberg's soft-graviton theorem,…
Probing Bose-enhanced Inflaton Decay with Gravitational Waves
Nicolás Bernal, Quan-feng Wu, Xun-Jie Xu +1
We investigate cosmic reheating dynamics in the presence of a transient condensate formed by bosonic decay products of the inflaton. We show that the emergence of such a condensate…
Sterile Neutrino Dark Matter as a Probe of Inflationary Reheating
James M. Cline, Yong Xu
Sterile neutrinos offer a minimal and testable explanation for dark matter (DM), with their radiative decay actively searched for in X-ray observations. We show that cold sterile n…
