This $1,945,592 federal Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences (MPS) program supports measurements of the cosmic microwave background (CMB) using the South Pole Telescope (SPT) and its SPT-3G camera. The award will enable expanding the sky coverage of the unprecedented depth, resolution, and polarization measurements provided by SPT-3G. These CMB temperature, polarization, and lensing data play a central role in probing current cosmological questions and testing the standard cosmological model. Additionally, the award will support using the high-resolution SPT-3G data to delens the degree-scale data from the BICEP array, increasing the power to detect primordial gravitational waves by over 2.5 times. The award will also fund an internship program with Joliet Junior College to engage underrepresented students in the SPT research activities.
