On the Hamilton-Jacobi approach to inflation beyond slow roll
Danilo Artigas, Emmanuel Frion, Tays Miranda +2
The Hamilton-Jacobi approach is a powerful tool to describe super-Hubble dynamics during cosmological inflation in a non-linear way. A key assumption of this framework is to neglec…
Bayesian analysis of a Unified Dark Matter model with transition: can it alleviate the tension?
Emmanuel Frion, David Camarena, Leonardo Giani +4
We consider cosmological models in which Dark Matter (DM) and Dark Energy (DE) are described by a single component, dubbed Unified Dark Matter (UDM) models, in which the DE-like pa…
Primordial black holes from a curvaton scenario with strongly non-Gaussian perturbations
Andrew D. Gow, Tays Miranda, Sami Nurmi
We investigate the production of primordial black holes (PBHs) in a mixed inflaton-curvaton scenario with a quadratic curvaton potential, assuming the curvaton is in de Sitter equi…
