SUMMARY:Mapping Mass Across The Sky: CMB Lensing\, Past and Future - Blake

DESCRIPTION:Measurements of gravitational lensing in the Cosmic Microwave 
 Background\n(CMB) directly probe the projected distribution of dark matter
  out to\nhigh redshifts. The CMB lensing maps thus encode a wealth of info
 rmation\nabout neutrino and dark energy properties\, and can also be used 
 to\nimprove constraints on inflationary tensor fluctuations. After briefly
 \nreviewing what we have learned from past work on CMB temperature lensing
 \n(e.g.\, with ACT and Planck)\, I will discuss new\, exploratory CMB\npol
 arization lensing measurements with the POLARBEAR and ACTPol\nexperiments.
  Finally\, I will explain the great scientific returns we can\nexpect from
  similar CMB polarization lensing surveys in just the next\nfew years. \n
