Observational constraints on Luciano-Saridakis holographic dark energy

First observational assessment of an extended holographic dark energy model arising from the Luciano–Saridakis generalized entropy, which includes both standard holographic dark energy and ΛCDM as limiting cases. Using Cosmic Chronometers, Pantheon+ & SH0ES, DESI DR2 BAO and Planck 2018 CMB data, the model provides an excellent fit to the combined dataset, with preferred solutions close to ΛCDM.
