Forecast and analysis of the cosmological redshift drift
Ruth Lazkoz, Iker Leanizbarrutia, Vincenzo Salzano
The cosmological redshift drift could lead to the next step in high-precision cosmic geometric observations, becoming a direct and irrefutable test for cosmic acceleration. In orde…
Cosmological constraints on a unified dark matter-energy scalar field model with fast transition
Iker Leanizbarrutia, Alberto Rozas-Fernández, Ismael Tereno
We test the viability of a single fluid cosmological model containing a transition from a dark-matter-like regime to a dark-energy-like regime. The fluid is a k-essence scalar fiel…
Crossing SNe Ia and BAO observational constraints with local ones in hybrid metric-Palatini gravity
Iker Leanizbarrutia, Francisco S. N. Lobo, Diego Saez-Gomez
In this paper, we consider the recently proposed hybrid metric-Palatini gravitational theory, which consists of adding to the Einstein-Hilbert Lagrangian an term c…
