A possible geometrical origin of the accelerated expansion of the universe
Ariadna Montiel, Nora Bretón, Rubén Cordero +1
The modified geodetic brane cosmology (MGBC) is tested with observational data. The MGBC is derived from the geodetic brane gravity action corrected by the extrinsic curvature of t…
Observational constraints from SNe Ia and Gamma-Ray Bursts on a clumpy universe
Nora Bretón, Ariadna Montiel
The luminosity distance describing the effect of local inhomogeneities in the propagation of light proposed by Zeldovich-Kantowski-Dyer-Roeder (ZKDR) is tested with two probes for…
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…
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…
