Connection details

Parallels 5 and 6, Session D. Wednesday April 1, 11:30 AM to 12:30 PM pacific.

Monitor: TBD

Scribe: TBD


  • Presentation / discussion of new developments in simulation techniques, codes, since the last meeting.
  • Identify the other working groups with science cases relying on Galactic foreground modeling (low-ell / BB, extragalactic foregrounds, etc)
    • What are the conclusions of the previous data challenges for these groups, in what direction does the foreground modeling require more complexity.
  • Are we prepared to provide the simulations that will be required to answer outstanding science questions for CD1.
    • What trade off studies are being looked at, will these require new foreground modeling efforts?
    • Are existing simulations sufficient for the next data challenge?


  • Data challenge paper and next steps (Victor, 10)
  • DC06 (Caterina, 10)
  • PySM3 (Andrea, 10)
  • Filament-based models (Carlos, 15)
  • Frequency decorrelation (Brandon, 15)


  • Neural Net Models, Dust (Ben, 15)
  • Neural Net Models, Synchrotron (Giuseppe, 15)
