Description
The South Pole Telescope is a dedicated 10-meter cosmic microwave background (CMB) telescope at the Amundsen-Scott station in Antarctica, and its current receiver, SPT-3G, equipped with 16,000 detectors in three millimeter-wave bands, has been used to map large areas of the sky since 2017. The combination of large primary mirror and high detector count allows us to produce high-resolution, low-noise maps of the southern sky in temperature and polarisation. These data are rich in cosmological information and power an array of science cases, such as primary CMB anisotropies, secondary CMB anisotropies (including lensing), cluster cosmology, astrophysical sources, and Galactic science. In this talk, I present an overview of the latest SPT-3G results, with a focus on the cosmological analysis of CMB temperature, polarisation, and lensing power spectra derived from two years of observations of a 1500 square degree field. I give an overview of analyses in progress that use data of up to 25% of the sky and discuss the future of the telescope.
