Cosmological data analysis of f(R) gravity models
Z. Girones, A. Marchetti, O. Mena +2
A class of well-behaved modified gravity models with long enough matter domination epoch and a late-time accelerated expansion is confronted with SNIa, CMB, SDSS, BAO and H(z) gala…

Instabilities in dark coupled models and constraints from cosmological data
L. Lopez Honorez, 0. Mena
Coupled dark matter-dark energy systems can suffer from non-adiabatic instabilities at early times and large scales. In these proceedings, we consider two parameterizations of the…

The dark side of curvature
G. Barenboim, E. Fernandez-Martinez, O. Mena +1
Geometrical tests such as the combination of the Hubble parameter H(z) and the angular diameter distance d_A(z) can, in principle, break the degeneracy between the dark energy equa…
