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…

Preheating with deep learning
Jong-Hyun Yoon, Simon Cléry, Mathieu Gross +1
We apply deep learning techniques to the late-time turbulent regime in a post-inflationary model where a real scalar inflaton field and the standard model Higgs doublet interact wi…

Probing Reheating with Graviton Bremsstrahlung
Nicolás Bernal, Simon Cléry, Yann Mambrini +1
We investigate the stochastic gravitational wave (GW) spectrum resulting from graviton bremsstrahlung during inflationary reheating. We focus on an inflaton oscillating around…
