Observational constraints on Luciano-Saridakis entropic cosmology
MatÃas Leizerovich, Susana J. Landau, Giuseppe Gaetano Luciano +2
A recently proposed generalized entropy by Luciano and Saridakis extends the standard Boltzmann-Gibbs and Bekenstein-Hawking framework through a microscopically motivated construct…
Geometric Cosmology models: statistical analysis with observational data
MatÃas Leizerovich, Luisa G. Jaime, Susana J. Landau +1
Although the standard cosmological model is capable of explaining most current observational data, it faces some theoretical and observational issues. This is the main motivation f…
Generalized tension metrics for multiple cosmological datasets
MatÃas Leizerovich, Susana J. Landau, Claudia G. Scóccola
We introduce a novel estimator to quantify statistical tensions among multiple cosmological datasets simultaneously. This estimator generalizes the Difference-in-Means statistic, $…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Cosmological perturbations with ultralight vector dark matter fields: numerical implementation in CLASS
Tomás Ferreira Chase, MatÃas Leizerovich, Diana López Nacir +1
In this work we consider a dark matter candidate described by an ultralight vector field, whose mass is in principle in the range . T…
On Geometric Cosmology
Gustavo Arciniega, Luisa G. Jaime, Susana J. Landau +1
We present a modification to General Relativity by making a redefinition of the coupling constant in front of the Ricci curvature scalar along with the Generalized Quasi-topologica…
