简介
We present measurements of the -mode () polarization power spectrum and temperature--mode () cross-power spectrum of the cosmic microwave background using data collected by SPT-3G, the latest instrument installed on the South Pole Telescope. This analysis uses observations of a region at 95, 150, and 220 GHz taken over a four-month period in 2018. We report binned values of the and power spectra over the angular multipole range , using the multifrequency data to construct six semi-independent estimates of each power spectrum and their minimum-variance combination. These measurements improve upon the previous results of SPTpol across the multipole ranges for and for , resulting in constraints on cosmological parameters comparable to those from other current leading ground-based experiments. We find that the SPT-3G data set is well fit by a …
