Gravitational waves from oscillons after inflation

12 Apr 2018 Antusch Stefan Cefala Francesco Orani Stefano

We investigate the production of gravitational waves during preheating after inflation in the common case of field potentials that are asymmetric around the minimum. In particular, we study the impact of oscillons, comparatively long lived and spatially localized regions where a scalar field (e.g. the inflaton) oscillates with large amplitude... (read more)
