Description

I will review briefly how inflation is expected to generate a stochastic background of primordial gravitational waves (GWs). Then, I will discuss how such GWs can be enhanced by a stiff period following inflation, enough to be observable. I will present examples of this in the contact of hybrid inflation with alpha-attractors, or a period of hyper-kination in Palatini gravity.
