Attendance: Brendan, Raphael, Amy, Al, Shaul, Julian
Notes by: Raphael

• Finalize dates + time for Foregrounds workshop (Raphael)
• Communicate with Nobu, Mark/Bill re science workshop (Shaul)

• Foregrounds
  • Currently aiming for last week of October or first week of November
  • Some rooms cost money. Shaul says to not worry about cost of rooms.
  • Raphael says he would have time to finalize dates and rooms during the week of July 17, when he is back at San Diego
• Science + Complementarity
  • Shaul talked with Mark. Some preference for May 2018
  • 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. Shaul suggested that they focus on technology or systematics, to complement our 'science and complementarity' later in the year.
  • SH: Should workshops be endorsed by both teams? May not be good at this point?
  • Shaul to communicate with Mark/Bill, and Nobu (LiteBIRD)

• Update from Fundamental Physics WG - Raphael
  • Slides posted
  • At this point need more input regarding target sensitivities

• Update from Extragalactic WG - Nick Battaglia
  • Recently formed extragalactic science working group, currently 15 members (+pending)
  • current approach: extragalactic science cases given CORE design
  • Galaxy clusters: - finding clusters, cosmology, CIB and radio contamination, y-maps, individual tSZ, kSZ, and rSZ for cluster science
  • Galaxy formation at z > 2 - properties of star-formation (SF) during the peak of SF via the CIB
  • Velocity fields - cosmology, contamination, systematics
  • Thermodynamic of galaxy formation - feedback, non-thermal pressure, ionized baryon content
  • Reionization - Optical depth constraints, kSZ power spectrum, mid-point and duration of reionization
  • Gravitational lensing? Need to involve experts in lensing/delensing, currently involved in extragalactic science working group
  • SH: what resolution is needed? at 150 GHz CMBP will not have 1' resolution. NB: OK to have 1' at the higher frequencies to complement ground-based telescopes. 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? Amy: we can accommodate 150 Mbits/s for approximately 2 hours a day
  • SH: What frequencies are important for cluster science? NB: up to 500-600 GHz

• moved to next telecon
