Observational evidence for Early Dark Energy as a unified explanation for Cosmic Birefringence and the Hubble tension
Joby Kochappan, Lu Yin, Bum-Hoon Lee +1
We test the =3 Ultralight Axion-like model of Early Dark Energy (EDE) with the observationsof the mode of the cosmic microwave background (CMB) radiation, and local expansi…
