| 英文摘要 | The Hubble tension might be resolved by injecting a new energy component, called early dark energy (EDE), prior to recombination. An anti-de Sitter (AdS) phase around recombination can make the injected energy decay faster, which thus allows a higher EDE fraction (so larger H-0) while prevents degrading the CMB fit. In this work, we test the AdS-EDE model with CMB and large-scale structure (LSS) data. Our CMB dataset consists of low-l part of Planck TT spectrum and SPTpol polarization and lensing measurements, since this dataset predicts the CMB lensing effect consistent with ACDM expectation. Combining it with BAO and Pantheon data, we find the best fit values H-0 = 71.92 km/s/Mpc and H-0 = 73.29 km/s/Mpc without and with the SH0ES prior, respectively. Including cosmic shear and galaxy clusters data, we have H-0 = 71.87 km/s/Mpc and S-8 = 0.785, i.e., only 1.3 sigma discrepancy with direct S-8 measurement. |
