Description
The South Pole Telescope Shirokoff Line Intensity Mapper (SPT-SLIM) is an experiment to demonstrate the use of superconducting on-chip spectrometers for millimeter-wave line intensity mapping. SPT-SLIM is optimized to detect redshifted carbon monoxide (CO) line emission from high-redshift ( 0.5 < z < 2) galaxies in the 2 mm atmospheric window as a pathfinder for future high-redshift LIM cosmology experiments. The instrument achieved first light during its deployment in the 2024-2025 austral summer and successfully completed a two-week observing campaign. In this talk, I will present an overview of the SPT-SLIM instrument design and describe its commissioning and Y1 performance. I will share early results from the initial observing run and discuss the prospects for a longer survey with upgraded instrumentation during the 2025-2026 austral summer.
