| Abstract: |
The Atacama Cosmology Telescope (ACT) is surveying the microwave sky at 148, 218, and 280 GHz with arcminute resolution. ACT has measured 7 "peaks" in the CMB power spectrum, detected lensing of the CMB, found dozens of new clusters, and placed new constraints on cosmological parameters and neutrino properties. The detection of CMB lensing enables a detection of dark energy using CMB observations alone. I will review these recent results. I will then discuss plans for a much more sensitive survey with our next generation polarization sensitive camera and the potential science return from combining ACTPOL measurements with SUMIRE observations of galaxy images and redshifts. |
