The Atacama Cosmology Telescope: An Update
Das, Sudeep (UC Berkeley)

Over the coming decade, tiny fluctuations in temperature and polarization of the Cosmic Microwave Background (CMB) will be mapped with unprecedented resolution. These new arc-minute resolution observations are shedding new light on the physics of the early universe and the neutrino sector. These observations are also allowing us to measure the gravitational lensing of the CMB by intervening large scale structure. CMB lensing will probe the growth of structure over cosmic time, helping constrain the total mass of neutrinos and the behavior of dark energy. In the first part of the talk, I will review the recent progress made with Atacama Cosmology Telescope. In the second part, I will discuss the first internal detection and the scientific potential of the CMB lensing signal.
