Abstract: We will review motivations for cosmological inflation, and fundamental observables. We will then discuss signatures that can arise from the coupling of a pseudo-scalar inflaton to gauge fields. The coupling can naturally lead to a strong amplification of gauge modes, that can in turn source large density perturbations and gravitational waves, both at extra-galactic (thus affecting the Cosmic Microwave Background observations) and at interferometer scales (such as Advanced LIGO and LISA).
