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, $…
Evolution of linear matter perturbations with error-bounded bundle physics-informed neural networks
Luca Gomez Bachar, Augusto T. Chantada, Susana J. Landau +2
We consider the evolution of linear matter perturbations in the context of the standard cosmological model (CDM) and a phenomenological modified gravity model. We use the physi…
The frozen vanilla model: Exploring dark sector interactions with delta effective theories
MartÃn G. Richarte, Luiz F. Guimarães, Susana J. Landau +1
In this paper, we introduce a new interacting mechanism within the dark sector, encompassing both dark energy and dark matter, while grounding our analysis in the familiar framewor…
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…
