Hubble tension and small-scale inhomogeneities on light propagation
Lucila Kraiselburd, Cassio Pigozzo, Susana J. Landau +1
Context. A major observational challenge within the standard cosmological framework is the Hubble tension, a statistically significant () disagreement between the Hubble…
Probing the H0 Tension with Holographic Dark Energy in Unimodular Gravity: Insights from DESI DR2
Francisco Plaza, Gabriel León, Lucila Kraiselburd
Motivated by the recent baryon acoustic oscillation measurements of DESI DR2 collaboration, this works presents an extended analysis of a cosmological model based on holographic da…
Testing f(R)-gravity models with DESI DR2 2025-BAO and other cosmological data
Francisco Plaza, Lucila Kraiselburd
Motivated by the new BAO data and the significant results recently published by the DESI DR2 Collaboration, this study presents a Markov Chain Monte Carlo (MCMC) analysis of all cu…
Testing f (R) gravity models with DESI-BAO and other cosmological data
Francisco Plaza, Lucila Kraiselburd
In this paper, we conduct a statistical analysis of various cosmological models within the framework of f (R) gravity theories, motivated by persistent challenges in modern cosmolo…
