South Pole Telescope: Recent Results and Future Directions
Adam Anderson
University of Chicago

The South Pole Telescope (SPT) is a 10-meter millimeter telescope located at Amundsen-Scott South Pole Station---one of the world's best sites for observing the cosmic microwave background (CMB). Since 2018, the current SPT-3G camera has been used to make the deepest observations of the CMB at arcminute resolution. In the first part of my talk, I will highlight several key results from this growing dataset, including recent constraints on cosmological parameters from measurements of the CMB temperature and polarization power spectra. Beyond CMB science, the SPT is also a uniquely powerful platform for field-testing new detector technology. Line-intensity mapping (LIM) of far-IR emission lines at millimeter wavelengths is an emerging and potentially powerful cosmological probe. We have built and deployed a novel camera, called SPT-SLIM, which uses an array of superconducting kinetic inductance detectors (KIDs) in an on-chip spectrometer configuration, to perform a LIM survey of redshifted CO emission with the SPT. I will review the design and status of SPT-SLIM and discuss future cameras being developed for the SPT.
