Description

This project will conduct measurements of the 14-billion-year-old cosmic microwave background (CMB) with the South Pole Telescope (SPT) to address some of the most basic and compelling questions regarding the origin and composition of the universe. The telescope's siting is ideal for ultra-low-noise imaging surveys of the sky at the millimeter and submillimeter radio wavelengths. This unique geographical location allows SPT to obtain extremely sensitive 24/7 observations of targeted, low-galactic, foreground regions of the sky. The telescope's third-generation SPT-3G receiver has 16,000 detectors configured for polarization-sensitive observations in three millimeter-wave bands. The proposed operations also support SPT's critical role in the Event Horizon Telescope (EHT), a global array of telescopes to image the event horizon around the black hole at the center of the Milky Way Galaxy.

Field Season Overview

On-site fieldwork for the upcoming season includes: 1) Service, upgrades, and maintenance of SPT-3G and EHT telescope components and computer systems; 2) Cryogenic maintenance of the SPT-3G and optics cryostats; 3) Winterover training; and 4) Installation of the SPT-SLIM instrument (NSF AST-2108763) followed by several weeks of test observations to demonstrate new on-chip spectrometer detector technology and constrain the molecular gas content of distant galaxies.
