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…
