Description

SPT-3G, the third-generation camera on the South Pole Telescope (SPT-3G), is being used to observe the cosmic microwave background (CMB) anisotropies to unprecedented depth at arcminute resolution. The temperature and E-mode polarization anisotropies of the CMB provide a wealth of information on the composition and evolution of the universe. This talk presents the upgraded cosmological analysis of the TT, TE and EE power spectra based on data collected in 2019-2020 and associated maps. LCDM parameter constraints will be comparable to Planck’s, while remaining mostly independent from the satellite experiment, thus allowing to test the consistency of the data sets and probe evidence of physics beyond the standard model. Combined with 2019-2020 SPT-3G CMB lensing reconstruction and other experiments, these results will produce some of the tightest constraints on cosmological parameters to date.
