| 英文摘要 | We investigate the constraints on early dark energy (EDE) by combining the most recent CMB dataset favors nonzero EDE fractions and large Hubble constants. The inclusion of BAO + Pantheon data has little effect on the results, leads to H0 = 71.6(72.9)+2.0???1.5 and 73.17(72.74)+0.55 EDE and AdS-EDE, respectively. The axionlike EDE can fit the data significantly better (????2 ??? ???10) than ACDM, which is mainly driven by the ACT data. It is found again that if the current H0 measured locally is correct, complete resolution of the Hubble tension seems to be pointing toward a scale invariant HarrisonZeldovich spectrum of primordial scalar perturbation, i.e., ns = 1 for H0 ??? 73 km/s/Mpc. |
