How Holographic is the Dark Energy? A Spline Nodal reconstruction approach
Miguel A. Zapata, Gabriela Garcia-Arroyo, Shahnawaz A. Adil +1
The paper investigates a generalized holographic dark energy model by reconstructing its density‑horizon relation with a spline‑based non‑parametric function and tests it against c…
Towards a complete scheme of cosmological neutrino self-interactions: Collision term for a wide range of mediator masses
Ivan Pérez-Castro, Josue De-Santiago, Gabriela Garcia-Arroyo +2
Neutrino self-interactions (NSI) offer a potential pathway to address anomalies in standard cosmology and explain existing cosmological tensions. In this work, we present a novel f…
Data-driven modeling of rotation curves with artificial neural networks
Gabriela Garcia-Arroyo, Isidro Gómez-Vargas, J. Alberto Vázquez
Galactic rotation curves are crucial for understanding the distribution of mass in galaxies. Despite advances in precision observations, there are discrepancies between the inferre…
Resonant neutrino self-interactions: Insights from the full shape galaxy power spectrum
Hernán E. Noriega, Josue De-Santiago, Gabriela Garcia-Arroyo +2
This paper investigates resonant neutrino self-interactions in cosmology by employing, for the first time, the effective field theory of large-scale structure to model their impact…
Resonant neutrino self-interactions and the tension
Jorge Venzor, Gabriela Garcia-Arroyo, Josue De-Santiago +1
In this work, we study the previously unexplored resonant region of neutrino self-interactions. Current disagreement on late and early time observations of the Universe expansion c…
Cosmological Parameter Estimation using Particle Swarm Optimization
Daniel Morales Hernández, Daniel Morales Hernandez, Gabriela Garcia-Arroyo +1
The quest for a theoretical framework and ingredients that capture our current understanding of the cosmos has motivated the design of a large number of highly informative experime…
