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…
Testing the Equivalence Principle with Strong Lensing Time Delay Variations
Leonardo Giani, Emmanuel Frion
Strong lensing time delay measurements provide a valuable and almost model-independent tool for cosmological investigations. In this work we recognize that they also carry informat…
