Early dark energy does not restore cosmological concordance

Abstract

The authors provide a thorough study of a popular scenario (early dark energy EDE) to alleviate the tension in the measurements of the Hubble constant ${H}_{0}$, which either rely on early Universe probes and the cosmological standard model ($\mathrm{\ensuremath{\Lambda}}$CDM) or on late Universe probes through direct, local distant measurements. The authors show that the inclusion of numerous large-scale structure data is in conflict with the parameter space that lifts the ${H}_{0}$ tension and severely limits the existence of EDE and, thus, makes it very unlikely to resolve the tension.
