• Planning for PICO and Complementarity with Ground Workshop in the spring (Shaul)

Planning for PICO and Complementarity with Ground Workshop in the spring (Shaul)

• Organize now that there is a instrument baseline.
• Science talks by the various WGs, invite broad community aslo.
• How do we include the ground based community?
• Date: Was plan to coordinate with an S4 meeting. S4 is planning a 2-3 day March meeting, Shaul didn't hear strong enthusiam for coordination. Combining both may be a challenge.
  • Planned PICO dates, late April - early May.
  • S4 meeting is governance and tech development.
    • Julian: case for conjoined workshops is decreasing.
• Shaul: Each WG put forward a spokesperson for group's science topics. Complemenarity with ground would be additional speaker.
• Is a workshop useful?
  • Jim: Yes. Disucssions useful.
    • Lloyd: what is extragalactic complementarity?
      • Jim: should be significant. PICO gives higher frequencies. Complementarity could be developed.
• Shaul: Pre-workshop groundwork?
  • Jim: yes. To develop context, get ground sensitivities, calculate gain from PICO frequencies.
    • Lloyd: modeling extragalactic sky workshop, Jan 10-12th. Some of the work to connect PICO and ground could be then.
• Shaul: Can Dave/Raphael compile names of people to present science case?
  • Yes (Dave), Yes(Raphael).
• Shaul: Idea, science group leaders help organize. Shaul can lead.
  • ??Lloyd??: yes, can help.
• Known conflicts?
  • April APS meeting, 14-17th of April
  • Nick in Paris end of April - end of May. Notify him of scheduling soon.
• What about other communities to include?
  • Galactic (Dave, Laura)
  • Others? PICO will create a legacy archive. Should invite those who will utilize it.
  • Jim: Important to increase visibility to non-CMB scienctists. Extragalactic has some of these connections.
  • Dave: Will ping EG group about connections to other ideas
• Locations?
  • Julian: Cheap. Easy flights and cheap accomidation.
  • Shaul: Minnesota can host, but doesn't need to. Anyone can volunteer.
  • Jim: Caltech, Pasendena?
    • Shaul: LiteBIRD and foregrounds workshop in California. Geographic balance would be nice.
    • Jim: Can talk with David Spurtle about Flatiron institute in NY. Shaul/Julian: NY is expensive, but maybe Flatiron can subsidize? Jim: Will ask.
• Shaul will start planning, begin putting together speaker list.
  • will form smaller committee. Expect emails from Shaul.
  • want skeleton program in short term so this can be announced.
