Attendance: Shaul H, Jim Bartlett, Dan Green, Amy T., Alex van Engleen, Nick B., Rafael F., Colin Hill

Notes by: Karl Young

• Review of Draft Report and next steps
  • Report schedule is here
  • GitHub repo for Report (for push access, send GitHub user name to Shaul; everyone can pull)
  • Current List of action items below

• Introduction: Dan/Raphael to contribute 1.5 pages introduction.
• Fundamental Physics (Dan, Raphael)
  • Raphael to calculate new sigma® using the 'requirements' (not the 'CBE' = goals)
  • Any material needed from Alex regarding delensing? (other lensing science is later)
  • include DM text from Vera
  • include cosmic birefringence from Vera
  • include primordial magnetic fields from Levon
  • (Revise neutrino mass figure with sigma(tau) = 0.007? (Planck2018-VI))
  • (Several references missing in Light Relics)
• Cosmic Structure Formation and Evolution (Nick, Colin, Alex, Jim?)
  • Need reionization text + Forecasts
  • Need lensing text + forecasts
    • Coordinate with Marcel regarding cross-correlations with other surveys?
  • Need text for SZ science
• Galactic Structure and Star Formation (Laura, Dave)
  • Text too long
  • Need to clarify SO9 of STM
  • Need references
• Separating the Signals (aka 'foregrounds') (Jacques, Clem)
  • Change tone to discuss array of signals rather than 'foregrounds'?
  • Need (to complete analysis and) text from Clem, Soumen, Belen
• Systematics
  • much of text in place. Needs detailed edit. Brendan busy with spherex.
• Measurement Requirements (Shaul)
  • Need text

Reminder of schedule:

• 2nd level draft by Oct. 1. within 5-10% of length targets. Ready to massage text for flow and smaller details.
  • have all figures
  • will go to JPL for a review first 2 weeks of Oct.

Status of report

• Introduction: Dan/Raphael to contribute 1.5 pages introduction.
  • Text by 9/19
  • DG and RF will work on 'State of the Art' as much as they know about and Shaul will add experimental details
• Fundamental Physics (Dan, Raphael)
  • Raphael to calculate new sigma® using the 'requirements' (not the 'CBE' = goals)
    • RF: These are Fischer matrix. No one will believe them. We need full foregrounds/maps numbers for final version. With r ~ 10^-4 which is the goal. Will generate Fischer #'s in 1 week.
  • Any material needed from Alex regarding delensing? (other lensing science is later)
    • RF/AE: RF has this covered. current power spectrum methods are fine for now.
  • include DM text from Vera
  • include cosmic birefringence from Vera
  • include primordial magnetic fields from Levon
    • RF in contact on 3 above. Will pass on tight schedule. Specs for Levon at top of main wiki page.
  • (Revise neutrino mass figure with sigma(tau) = 0.007? (Planck2018-VI)) DG doing
  • (Several references missing in Light Relics) RF fixing
• Cosmic Structure Formation and Evolution (Nick, Colin, Alex, Jim?)
  • Need reionization text + Forecasts
    • CH added text today.
    • NB to make figure. CBE and requirements. 68%,95% contours.
  • Need lensing text + forecasts
    • Coordinate with Marcel regarding cross-correlations with other surveys?
  • Structure and Gravitational Lensing
    • AE working on. Text by 9/19
    • Work with Marcel Schmittfull and JB on cross-correlations and CMB halo
    • CH: be sure this connect to nuetrino mass in fundamental physics section.
  • Need text for SZ science
    • CH add text and figure (maybe placeholder) by 9/19
    • CH: focusing on tSZ. mentioning connection between high frequency and ground experiments. This was removed from STM since much of the sensitivity is from high resolution ground. But still discuss tSZ and kSZ here.
• Galactic Structure and Star Formation (Laura, Dave)
  • Text too long, Need to clarify SO9 of STM, * Need references
  • SH: we're in contact. Laura/Dave pruning by 9/19
• Separating the Signals (aka 'foregrounds') (Jacques, Clem)
  • Change tone to discuss array of signals rather than 'foregrounds'?
    • No objections.
  • Need (to complete analysis and) text from Clem, Soumen, Belen
    • 1 sentence from Soumen is, 'For simple and moderate models the cleaning does ok down to r ~10^-3. Does not do well for most complex models.'
    • Telecons are Thursday 10am CST if people can/want to join.
    • SH to try to get Clem and RF in 9/13 telecon to discuss details
• Systematics
  • much of text in place. Needs detailed edit. Brendan busy with spherex.
  • SH: Brendan will be back end of Sept.
• Measurement Requirements (Shaul)
  • Need text
  • SH: 1/2 done. finish text by 9/13 or 9/14.
  • Goes to AT for next review.
• Later sections are behind JPL firewall.
• Tech Maturation is written by Roger O'Brient and being sent to JPL review. Should see it in 1-2 weeks.
