Title: Cosmology fromf 17,000 Feet: Results from the Atacama Cosmology Telescope

Abstract:

The Atacama Cosmology Telescope (ACT) is a 6-meter diameter telescope observing the Cosmic Microwave Background (CMB) high in the Chilean Andes. ACT observed the intensity of the CMB from 2007-2010, and is about to begin polarization observations. We present results from the full ACT intensity-only dataset, such as the first direct detection of the motion of galaxy clusters through the kinematic Sunyaev-Zeldovich effect and the first detection of the lensing of the CMB through its signature on the 4-point function. We also combine ACT data with results from other CMB experiments (Planck,WMAP, South Pole Telescope) and complementary cosmological data such as measurements of the Hubble Constant and baryon acoustic oscillations.
