| Abstract: | Gravitational lensing of the CMB is rapidly emerging as a new precise cosmological tool. There now exist maps of the matter distribution (including dark matter) over large swaths of the sky, allowing interesting new measurements of the matter power spectrum and providing new insights into the relation between how galaxies populate the mass distribution. Lensing also generates CMB polarization "B-modes," an effect recently measured with the South Pole Telescope. |
