CMB Polarization with the South Pole Telescope

Duncan Hanson

Measurements of polarization in the Cosmic Microwave Background (CMB) are our best hope to measure the amplitude and scale of gravity waves in the early Universe. They also have the power to provide an (astrophysical) determination of the absolute neutrino mass scale. For the past two years, we have been surveying the polarization of the CMB with unprecedented precision and resolution using a dedicated 10 meter telescope located at the geographic South Pole. I'll discuss recent progress and future ambitions.
