Description
I will discuss the role of gauge fields during inflation, with particular emphasis on scenarios where they are coupled to an axion-like inflaton. Such couplings can lead to rich dynamics with observable consequences, including the production of chiral primordial gravitational waves and primordial black holes. In addition, gauge fields can play an important role in reheating and provide a source of primordial magnetic fields, offering potential links between inflationary physics and present-day astrophysical observations.
