Cosmology with the South Pole Telescope

The South Pole Telescope (SPT) is a new, and the largest, telescope
deployed in Antarctica that is designed to study the Cosmic Microwave
Background.  This telescope provides astronomers a powerful new tool
to explore dark energy, the mysterious phenomena that may be causing
the universe to accelerate. The SPT has covered a 2500 square degree
sky area measuring CMB anisotropies and detecting galaxy clusters and
is a major instrument to detect the secondary anisotropies such as CMB
lensing and the Sunyaev-Zeldovich (SZ) effect power spectrum.  I will
give a brief theoretical overview of the SZ effect and the CMB
lensing. I will discuss some of the exciting recent and upcoming
results about neutrino mass measurements and dark energy from
different SPT observations.
