Science with the South Pole Telescope

The South Pole Telescope is a 10-meter telescope designed to survey the millimeter-wave sky, taking advantage of the exceptional observing conditions at the NSF South Pole Station. The first phase of the project involves a survey of many hundreds of square degrees of the southern sky, with measurements at 90GHz, 150GHz, and 220GHz. The data from this first phase can be used to detect large numbers of galaxy clusters for Dark Energy studies, test the properties of individual clusters, explore millimeter-wave sources, and probe the Cosmic Microwave Background (CMB) power spectrum at small angular scales. In the second phase of the project, we will install polarization-sensitive detectors and make measurements of the power spectrum of the polarization of the CMB. I will give an overview of these science goals, describe the most important features of the design of the instrument, and give some recent results.
