Power law cosmology model comparison with CMB scale information
Isaac Tutusaus, Brahim Lamine, Alain Blanchard +14
Despite the ability of the cosmological concordance model (CDM) to describe the cosmological observations exceedingly well, power law expansion of the Universe scale radius, $R(…
Dark sectors of the Universe: A Euclid survey approach
Isaac Tutusaus, Brahim Lamine, Alain Blanchard +3
In this paper we study the consequences of relaxing the hypothesis of the pressureless nature of the dark matter component when determining constraints on dark energy. To this aim…
Dark-energy dependent test of general relativity at cosmological scales
Yves Zolnierowski, Alain Blanchard
The CDM framework offers a remarkably good description of our universe with a very small number of free parameters, which can be determined with high accuracy from currently ava…
Constraints on dark energy evolution
L. D. Ferramacho, A. Blanchard, Y. Zolnierowski +1
We investigate a class of dark energy models in which the equation of state undergoes a rapid transition and for which the Hubble SN Ia diagram is known to be poorly discriminant.…
