Scientific paper

Arcminute resolution observations of the mm-wave sky are changing our view of the cosmic microwave background (CMB) in a fundamental way. Together with mapping out the acoustic features on the Silk damping tail of CMB, data from the Atacama Cosmology Telescope (ACT) are providing new insights into secondary CMB anisotropies and extragalactic point source populations that dominate the scene at small angular scales. I will describe the angular power spectrum measurements from ACT, and an ongoing search for the gravitational lensing signal in ACT maps.
