CMB Experiments as Wide Field Astrophysics Surveys

Abstract: There is still a lot of fundamental physics to learn from ongoing and future CMB experiments, but they now have sufficient depth that they can reasonably be thought of as mm-wave wide-area sky surveys, providing mm-wave perspectives on similar science themes traditionally done at visible wavelengths. This includes searches for interesting rare objects, like galaxy clusters and strong lenses, mapping the mass distribution with weak lensing, and tracking the time variable sky for solar system objects, stellar flares, and possible extragalactic transients.
