If you have a question about this talk, please contact Ryan Cooke.

CMB lensing measurements can directly map out the projected distribution of dark matter out to high redshifts. I will describe the first detection of the CMB lensing power spectrum with the Atacama Cosmology Telescope (ACT) and its cosmological implications, and will show current work on the lensing-quasar cross-correlation. Finally I will discuss prospects and challenges for near-future CMB lensing measurements using polarization data from ACT Pol.
