Monomial warm inflation revisited
Guillermo Ballesteros, Alejandro Pérez Rodríguez, Mathias Pierre
We revisit the idea that the inflaton may have dissipated part of its energy into a thermal bath during inflation, considering monomial inflationary potentials and three different…
Primordial black holes and gravitational waves from dissipation during inflation
Guillermo Ballesteros, Marcos A. G. García, Alejandro Pérez Rodríguez +2
We study the generation of a localized peak in the primordial spectrum of curvature perturbations from a transient dissipative phase during inflation, leading to a large population…
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…
The tension: vs.
Guillermo Ballesteros, Alessio Notari, Fabrizio Rompineve
We investigate whether the tension on between SHES 2019 and Planck 2018 can be alleviated by a variation of Newton's constant between the early and the lat…
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…
Detuning primordial black hole dark matter with early matter domination and axion monodromy
Guillermo Ballesteros, Julián Rey, Fabrizio Rompineve
We present a scenario that ameliorates the tuning problems present in models of primordial black hole dark matter from inflation. Our setup employs the advantages of gravitational…
