Dark energy constraints from Pantheon+ Ia supernovae data

Sergio Torres-Arzayus

Abstract: Measurements of the current expansion rate of the Universe, H0, using standard candles, disagree with those derived from observations of the Cosmic Microwave Background (CMB). This discrepancy, known as the Hubble tension, is substantial and suggests the possibility of revisions to the standard cosmological model (Cosmological constant Λ and cold dark matter -ΛCDM ). Dynamic dark energy (DE) models that introduce deviations in the expansion history relative to ΛCDM could potentially explain this tension. We us… Show more
