Title: Novel cosmological tests with precision CMB measurements
Abstract: High resolution cosmic microwave background (CMB) experiments provide views of the Universe both at redshift ~1100, when the primary CMB was produced, as well as an integrated view of the Universe between then and now, through CMB secondary anisotropies. In this talk, I will show that CMB secondary anisotropies contain a wealth of cosmological information and are becoming leading cosmological probes. I will present recent measurements from the Atacama Cosmology Telescope collaboration that have mapped out several of these effects. I will then highlight some challenges for these measurements with upcoming CMB experiments, and some unique opportunities, such as tests of the fundamental properties of our Universe.
