Description

In inflationary theories, single field models are typically considered subject to slow-roll conditions. However, as I will show in this talk, current observational constraints allow significant violations of these conditions. Focusing on non-Gaussian signals, I will discuss a variety of new observational signatures that can be found for fast-rolling single fields.
