A flashing beacon in axion inflation: recurring bursts of gravitational waves in the strong backreaction regime
Juan Garcia-Bellido, Alexandros Papageorgiou, Marco Peloso +1
The coupling between a pseudo-scalar inflaton and a gauge field leads to an amount of additional density perturbations and gravitational waves (GWs) that is strongly sensitive to t…

Instability in axion inflation with strong backreaction from gauge modes
Marco Peloso, Lorenzo Sorbo
We perform an analytical study of the stability of the background solution of the model in which an inflaton, through an axionic coupling to a gauge field, causes an amplifi…
