The cosmic microwave background (CMB) has proven to be a powerful probe of the physics and cosmology of our universe. Recent measurements have led to several exciting first detections, including gravitational lensing of the CMB, the discovery of massive galaxy clusters via the thermal Sunyaev-Zel'dovich effect, a measurement of the large-scale velocity field via the kinematic Sunyaev-Zel'dovich effect, and the “B-mode” component of the CMB polarization field. I will discuss these with a focus on the results of temperature and polarization measurements from the 6-meter Atacama Cosmology Telescope (ACT), and provide a brief update on the Advanced ACTPol project.
