Edges and Endpoints in 21-cm Observations from Resonant Photon Production
Andrea Caputo, Hongwan Liu, Siddharth Mishra-Sharma +3
We introduce a novel class of signatures---spectral edges and endpoints---in 21-cm measurements resulting from interactions between the standard and dark sectors. Within the contex…
Stochastic inflationary dynamics beyond slow-roll and consequences for primordial black hole formation
Guillermo Ballesteros, Julián Rey, Marco Taoso +1
We consider the impact of quantum diffusion on inflationary dynamics during an ultra-slow-roll phase, which can be of particular significance for the formation of primordial black…
Primordial black holes as dark matter and gravitational waves from single-field polynomial inflation
Guillermo Ballesteros, Julián Rey, Marco Taoso +1
We consider the possibility that the majority of dark matter in our Universe consists of black holes of primordial origin. We determine the conditions under which such black holes…
