First cosmological constraints on the Superfluid Chaplygin gas model
Ruth Lazkoz, Ariadna Montiel, Vincenzo Salzano
In this work we set observational constraints of the Superfluid Chaplygin gas model, which gives a unified description of the dark sector of the Universe as a Bose-Einstein condens…
Observational constraints on electromagnetic Born-Infeld cosmology
Nora Bretón, Ruth Lazkoz, Ariadna Montiel
The cosmological model consisting of an electromagnetic Born-Infeld (BI) field coupled to a Robertson-Walker geometry is tested with the standard probes of SNIa, GRBs and direct Hu…
GRB Hubble diagram and constraints on a Λ(t)CDM model
Hermano Velten, Ariadna Montiel, Saulo Carneiro
In previous papers, a cosmological model with constant-rate particle creation and vacuum term decaying linearly with the Hubble parameter was shown to lead to a good concordance wh…
Testing a DBI model for the unification of dark matter and dark energy with Gamma-Ray Bursts
Ariadna Montiel, Nora Bretón
We study the range of consistency of a model based on a nonlinear scalar field Dirac-Born-Infeld action for the unification of dark matter and dark energy using Gamma-Ray Bursts at…
