Observational constraints on Luciano-Saridakis holographic dark energy
Matías Leizerovich, Susana J. Landau, Giuseppe Gaetano Luciano +2
Holographic dark energy (HDE) models provide a natural framework for linking gravitational thermodynamics to the late-time accelerated expansion of the Universe. In this work, we i…
Observational constraints on Luciano-Saridakis entropic cosmology
Matías 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…
Generalized tension metrics for multiple cosmological datasets
Matías 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 physic…
Geometric Cosmology models: statistical analysis with observational data
Matías 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…
The frozen vanilla model: Exploring dark sector interactions with delta effective theories
Martín 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…
