Axio-Dilaton Dark Energy: A Dynamical Systems and Bayesian Inference Analysis
Mario Ramos-Hamud, Gabriela García-Arroyo, Fernando Quevedo +1
We initiate a systematic cosmological investigation of an axio-dilaton system governed by a curved field-space metric as generically motivated by supergravity and string compactifi…
Early against Late: A contrast on dark energy in the light of DESI DR2
Miguel A. Zapata, Karim Carrion, Gabriela Garcia-Arroyo
Recent findings from Dark Energy Spectroscopic Instrument (DESI) Baryon Acoustic Oscillation (BAO) measurements, combined with Type Ia supernovae and Cosmic Microwave Background (C…
Cosmological Constraints on Interacting Scalar-Field Dark Matter and Early Dark Energy mediated by a Kinetic Kernel
Gabriela Garcia-Arroyo, L. Arturo Ureña-López, J. Alberto Vázquez
In this work, we build a general framework for constraining interacting scalar fields with cosmological observations, applicable to a broad family of scalar--field potentials and i…
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…
Cosmological Parameter Estimation using Particle Swarm Optimization
Daniel Morales Hernandez, Gabriela Garcia-Arroyo, J. Alberto Vazquez
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…
How Holographic is the Dark Energy? A Spline Nodal reconstruction approach
Miguel A. Zapata, Gabriela Garcia-Arroyo, Shahnawaz A. Adil +1
In this work, we explore the generalized holographic dark energy (HDE) scenario. We relate the HDE density to the future-horizon scale via a non-parametric function, which is recon…
