Abstract
The authors present constraints on cosmological models obtained by using state-of-the-art methods on data from the South Pole Telescope (SPT-3G) experiment. Apart from several incremental improvements, the results are in general consistent with those obtained from other data sets and other experiments. In particular, the authors set the tightest constraint on the Hubble constant, ${H}_{0}$, from CMB power spectra to date, which is in $4.1\ensuremath{\sigma}$ tension with the most precise distance-ladder-based measurement of ${H}_{0}$.
