What is the impact of delensing on r, and on nt or BB wiggles?

  • Stephen Feeney: some forecasts of S4 performance:

What sensitivity and resolution do we need for the lensing map?

  • Is external lensing map good enough (e.g. CIB?) - No!
  • Blake: need high sensitivity lensing map. Plot shows residual delensed B-mode noise on large scales vs. noise of the high-res lens-reconstruction-experiment.
