Notes by: Raphael

• Update on Workshops
  1. Foregrounds - Raphael
     1. Currently aiming for last week of October or first week of November
  2. Science + Complementarity - Mark and/or Bill or Shaul

1. Current target date is May 2018
   1. JB: Possibly coordinate with series of workshops for LiteBIRD? Previous workshops in 12/15 (Japan) and 1/17 (Montreal) Third workshop proposed around 1/18
   2. SH: Should workshops be endorsed by both teams? May not be good at this point?

• Update from Fundamental Physics WG - Raphael
• Update from Extragalactic WG - Nick Battaglia

1. Recently formed extragalactic science working group, currently 15 members (+pending)
2. current approach: extragalactic science cases given CORE design
   1. Galaxy clusters: - finding clusters, cosmology, CIB and radio contamination, y-maps, individual tSZ, kSZ, and rSZ for cluster science
   2. Galaxy formation at z > 2 - properties of star-formation (SF) during the peak of SF via the CIB
   3. Velocity fields - cosmology, contamination, systematics
   4. Thermodynamic of galaxy formation - feedback, non-thermal pressure, ionized baryon content
   5. Reionization - Optical depth constraints, kSZ power spectrum, mid-point and duration of reionization
   6. Gravitational lensing? Need to involve experts in lensing/delensing, currently involved in extragalactic science working group

      JM: Why are Planck beams not diffraction limited at high frequencies?
      BC: Not enough signal band width
      JM: Can we handle signal band width for diffraction limited beams at ~800 GHz?
      SH, NB: What is needed for cluster science? 500-600 GHz?

• More on NASA slides (continuation from 2 weeks ago) - Shaul
  1. moved to next telecon
