Supporting Stations: South Pole Station
The South Pole Telescope (SPT) aids cosmological research by measuring the intensity and polarization anisotropy of the cosmic microwave background (CMB) radiation. The project's goal is detecting all galaxy clusters in this region of the sky through the spectral distortion they impart on the CMB. Called the Sunyaev-Zel'dovich effect, it has the remarkable property of being independent of the distance to the cluster. The second key project started in 2012 with the installation of an ultra-sensitive polarization receiver. Through measurements of the polarization, researchers can determine the sum of the masses of the neutrinos and either detect or set stringent upper limits on the energy scale of inflation.
Field Season Overview
The upcoming season is similar to last year in that SPT team members will conduct CMB measurements and will install the Event Horizon Telescope (EHT). Continued use of the MAPO machine shop as an overall station resources will be staffed by A-379-S personnel.
