New perspectives on constant-roll inflation
F. Cicciarella, J. Mabillard, M. Pieroni
We study constant-roll inflation using the -function formalism. We show that the constant rate of the inflaton roll is translated into a first order differential equation for th…

PBH dark matter from axion inflation
Valerie Domcke, Francesco Muia, Mauro Pieroni +1
Protected by an approximate shift symmetry, axions are well motivated candidates for driving cosmic inflation. Their generic coupling to the Chern-Simons term of any gauge theory g…

Primordial GWs from universality classes of pseudo-scalar inflation
Mauro Pieroni
In this contribution we discuss the possibility of generating an observable gravitational wave (GW) background by coupling a pseudo-scalar inflaton to some Abelian gauge fields. Th…
