Mapping Mass Across The Sky: CMB Lensing, Past and Future
If you have a question about this talk, please contact Helvi Witek.
Measurements of gravitational lensing in the Cosmic Microwave Background (CMB) directly probe the projected distribution of dark matter out to high redshifts. The CMB lensing maps thus encode a wealth of information about neutrino and dark energy properties, and can also be used to improve constraints on inflationary tensor fluctuations. After briefly reviewing what we have learned from past work on CMB temperature lensing (e.g., with ACT and Planck), I will discuss new, exploratory CMB polarization lensing measurements with the POLARBEAR and ACT Pol experiments. Finally, I will explain the great scientific returns we can expect from similar CMB polarization lensing surveys in just the next few years.
