Delensing

(Blake Sherwin, Olivier Dore, Chris Sheehy, Josquin Errard, Stephen Feeney, Alex van Engelen, Neelima Sehgal, Anthony Challinor...)

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


How does internal CMB delensing compare to external (e.g. CIB)?

  • Blake says external cleaning won't be good enough for 1 uK noise levels.

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

  • Blake: need high sensitivity lensing map
