On the dark contents of the Universe: A Euclid survey approach
Isaac Tutusaus, Brahim Lamine, Alain Blanchard
In this work we study the consequences of allowing non pressureless dark matter when determining dark energy constraints. We show that present-day dark energy constraints from low-…
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…
