Scale-dependent gravitational waves from a rolling axion
Ryo Namba, Marco Peloso, Maresuke Shiraishi +2
We consider a model in which a pseudo-scalar field rolls for some e-folds during inflation, sourcing one helicity of a gauge field. These fields are only gravitationally couple…

Trajectories with suppressed tensor-to-scalar ratio in Aligned Natural Inflation
Marco Peloso, Caner Unal
In Aligned Natural Inflation, an alignment between different potential terms produces an inflaton excursion greater than the axion scales in the potential. We show that, starting f…
