Dark Energy Survey Year 3 results: cosmology with moments of weak lensing mass maps
M. Gatti, B. Jain, C. Chang +107
We present a cosmological analysis using the second and third moments of the weak lensing mass (convergence) maps from the first three years of data (Y3) data of the Dark Energy Su…
Constant-roll inflation in the generalized SU(2) Proca theory
Juan C. Garnica, L. Gabriel Gomez, Andres A. Navarro +1
The generalized SU(2) Proca theory (GSU2P) is a variant of the well known generalized Proca theory where the vector field belongs to the Lie algebra of the SU(2) group of global tr…
Non-Abelian -term dark energy and inflation
Yeinzon Rodriguez, Andres A. Navarro
We study the role that a cosmic triad in the generalized Proca theory, specifically in one of the pieces of the Lagrangian that involves the symmetric version of t…
Scalar and vector Galileons
Yeinzon Rodriguez, Andres A. Navarro
An alternative for the construction of fundamental theories is the introduction of Galileons. These are fields whose action leads to non higher than second-order equations of motio…
The Vector Curvaton
Andres A. Navarro, Yeinzon Rodriguez
We analyze a massive vector field with a non-canonical kinetic term in the action, minimally coupled to gravity, where the mass and kinetic function of the vector field vary as fun…
Convergence of Scalar-Tensor theories toward General Relativity and Primordial Nucleosynthesis
A. Serna, J. -M. Alimi, A. Navarro
In this paper, we analyze the conditions for convergence toward General Relativity of scalar-tensor gravity theories defined by an arbitrary coupling function (in the Einstein…
Asymptotic and Exact Solutions of Perfect-Fluid Scalar-Tensor Cosmologies
A. Navarro, A. Serna, J. -M. Alimi
We present a method which enables exact solutions to be found for at homogeneous and isotropic scalar-tensor cosmologies with an arbitrary function and satisfying the genera…
