Description |
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. |
