Return to Inflation sessions page
Foregrounds
- What are our latest estimates of foreground levels post-Planck?
- What simulations and tools do we have for forecasting impact on r?
- What are still physical unknowns?
- Do we need new data at <40 GHz and >230 GHz?
- How important is large sky area?
Delensing
- What is the impact of delensing on r, and on nt?
- How does internal CMB delensing compare to external (e.g. CIB)?
- How important is it to have lensing map from the same instrument?
- What sensitivity and resolution do we need for the lensing map?
Foregrounds
- What are our latest estimates of foreground levels post-Planck? (Steve, Raphael...)
Can we make a new version of this figure:
- What simulations and tools do we have for forecasting impact on r? (Jacques, Raphael, Stephen F, Aurelien, Jo)
- What are still physical unknowns? (Al Kogut?)
Magnetic dust, spinning dust polarization, spatial dispersion of dust temperature/emissivity
- Do we need new data at <40 GHz and >230 GHz? (Jo)
- How important is large sky area?
===Delensing=== (Blake Sherwin, Olivier Dore, Chris Sheehy, Josquin Errard, Stephen Feeney)
- What is the impact of delensing on r, and on nt?
- 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?
