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…
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 c…
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…
Testing Modified Gravity theory (MOG) with Type Ia Supernovae, Cosmic Chronometers and Baryon Acoustic Oscillations
Carolina Negrelli, Lucila Kraiselburd, Susana J. Landau +1
We analyse the MOdified Gravity (MOG) theory, proposed by Moffat, in a cosmological context. We use data from Type Ia Supernovae (SNe Ia), Baryon Acoustic Oscillations (BAO) and Co…
Spatial variation of fundamental constants: testing models with thermonuclear supernovae
Carolina Negrelli, Lucila Kraiselburd, Susana J. Landau +1
Since Dirac stated his Large Number Hypothesis the space-time variation of fundamental constants has been an active subject of research. Here we analyze the possible spatial variat…
