Does Current Data Prefer a Non-minimally Coupled Inflaton?
Lotfi Boubekeur, Elena Giusarma, Olga Mena +1
We examine the impact of a non-minimal coupling of the inflaton to the Ricci scalar, , on the inflationary predictions. Such a non-minimal coupling is expected to be…
Phenomenological approaches of inflation and their equivalence
Lotfi Boubekeur, Elena Giusarma, Olga Mena +1
In this work, we analyze two possible alternative and model-independent approaches to describe the inflationary period. The first one assumes a general equation of state during inf…
On the current status of Modified Gravity
Lotfi Boubekeur, Elena Giusarma, Olga Mena +1
We revisit the cosmological viability of the Hu Sawicki modified gravity scenario. The impact of such a modification on the different cosmological observables, including gravi…
A model-independent fit to Planck and BICEP2 data
Laura Barranco, Lotfi Boubekeur, Olga Mena
Inflation is the leading theory to describe elegantly the initial conditions that led to structure formation in our universe. In this paper, we present a novel phenomenological fit…
