DESCRIPTION:The deflection of CMB photons by large-scale structures smooth
 s the observed CMB acoustic peaks and introduces a sizeable white noise co
 mponent in the polarization B-mode.\n\nIn order to achieve best constraint
 s on the inflationary perturbations tensor to scalar ratio\, upcoming low-
 noise polarization-based experiments must be able to undo these deflection
 s\, an operation called delensing.\n\nI will present the first detection o
 f B-mode delensing\, and first internal delensing of the CMB that we recen
 tly performed on Planck public maps\, as well as discuss methods and prosp
 ects for the future.
