Kavli Affiliate: George Efstathiou | Summary:Axion-like early dark energy (EDE) as an extension to $Λ$CDM has been proposed as a possible solution to the ‘Hubble tension’. We revisit this model using a new cosmic microwave background (CMB) temperature and polarization likelihood constructed from the it Planck NPIPE data release. In a Bayesian analysis, we find […]
