B-modes challenges: foregrounds and de-lensing

Foregrounds log-book

  • What are our latest estimates of foreground levels post-Planck?
  • What simulations and tools do we have for forecasting impact on r? (details for Tuesday, also incl delensing)
  • What are still physical unknowns?
  • Do we need new data at <40 GHz and >230 GHz? (and 60 GHz?)
  • How important is large sky area?
  • What is the path to a convincing claim that a B-mode signal is not foregrounds?

Delensing logbook

  • What is the impact of delensing on r, and on nt or BB wiggles?
  • What sensitivity and resolution do we need for the lensing map?
  • What are the frequency/foreground-removal requirements for the lensing map?
