Probing the H0 Tension with Holographic Dark Energy in Unimodular Gravity: Insights from DESI DR2

[2508.21175] Probing the H0 Tension with Holographic Dark Energy in Unimodular Gravity: Insights from DESI DR2 Skip to main content We gratefully acknowledge support from the Simons Foundation, member institutions , and all contributors.
We conclude that the present implementation of holographic dark energy in Unimodular Gravity, while theoretically appealing, does not alleviate the Hubble tension and is not statistically preferred by Bayesian criteria when compared with the standard $\Lambda$CDM model.
