Thermal Gravitational Waves During Reheating
Nicolás Bernal, Yong Xu
In this work, we revisit the generation of stochastic gravitational waves (GWs) from interactions in the thermal plasma. We extend the existing literature by incorporating the rehe…
Graviton- and Inflaton-mediated Dark Matter Production after Large Field Polynomial Inflation
Nicolás Bernal, Julia Harz, Martin A. Mojahed +1
Polynomial inflation is a simple cosmological scenario, which fits the cosmic microwave background data well. It provides testable predictions for the tensor-to-scalar ratio and th…
Probing Reheating with Gravitational Waves from Graviton Bremsstrahlung
Basabendu Barman, Nicolás Bernal, Simon Cléry +3
In this talk, based on arXiv:2301.11345, arXiv:2305.16388, arXiv:2311.12694, we discuss the production of primordial gravitational waves (GW) sourced by graviton bremsstrahlung dur…
Resonant Reheating
Basabendu Barman, Nicolás Bernal, Yong Xu
We investigate a novel reheating scenario proceeding through -channel inflaton annihilation, mediated by a massive scalar. If the inflaton oscillates around the minimum of a…
