Testing gravity using large-scale redshift-space distortions
(Oxford University Press, 2013)
We use luminous red galaxies from the Sloan Digital Sky Survey (SDSS) II to test the cosmological structure growth in two alternatives to the standard cold dark matter ( CDM)+general relativity (GR) cosmological model. ...
Matter bispectrum in cubic Galileon cosmologies
(IOP Science, 2013)
In this paper we obtain the bispectrum of dark matter density perturbations in the frame of covariant cubic Galileon theories. This result is obtained by means of a semi- analytic approach to second-order perturbations ...
