Abstract:
The 10-meter South Pole Telescope (SPT) is a millimeter wavelength  
telescope designed to conduct sensitive measurements of the cosmic 
microwave  background (CMB) at arc-minute resolution. The SPT has 
successfully conducted  a 2500 square degree survey to find clusters of 
galaxies from their  distortion of the CMB, known as the 
Sunyaev-Zel'dovich (SZ) effect. The  surface brightness of the SZ effect 
is redshift independent which allows a SZ  survey to provide a nearly 
mass limited cluster sample out to the earliest  epochs of cluster 
formation. The SPT has identified ~700 of cluster  candidates. Of these, 
~500 have been optically confirmed, with the majority  being newly 
discovered clusters at z > 0.5. I will summarize the main results  from 
the SPT cluster survey, including cosmological constraints from their  
measurement of the growth of structure.
