Measurement and Modeling of Polarized Atmosphere at the South Pole with SPT-3G

open access: yesThe Astrophysical Journal
We present the detection and characterization of fluctuations in linearly polarized emission from the atmosphere above the South Pole. These measurements make use of data from the SPT-3G receiver on the South Pole Telescope in three frequency bands ...
