FPC Meeting on 2019/06/14 13:30 - (JST)

Participants: Chunglee Kim, Kentaro Komori, Matteo Leonardi, Yuta Michimura, Atsushi Nishizawa, Kentaro Somiya, SH

Zoom meeting(2): https://zoom.us/j/6676627462

• Next meeting will be in middle July ? (doodle poll will be circulated).

• Back to FPC page

Action items

• Update science scenario with new scoring while keeping the optimistic case for the funding request (Nishizawa)
• Update technology section and add another column like "additive" in the technology scoring sheet (Somiya)
  • DECIGO, Optical levitation, icing of TM, cooling capacity(?), ...
• Science Figure of Merits (FoM) for each scenario (Haino, Nishizawa, ...)
• New sensitivity curves (Haino, ...)

Agenda

• Observing Scenario Paper (OSP) and O3 simulation (also at LIGO git)

  • "Another" final circulation of OSP and LVK-wide presentation will be made very soon. There has been a long delay because of the intensive discussions on the duration and timeline of O4 (and O5) by LVK management people.
  • For O3 simulation with KAGRA, SH was invited to LVK O3 task force and simulation results were reported in the last JRPC on June/6 (by Tagoshi-san). Our simulation results are under the review by L.Singer
• Updates on science scenario ?
  • O5 CBC (BBH, BNS, NSBH) simulations for O5 with several KAGRA's sensitivities are on-going
• Figure of merits for each science scenario
  • LF: BBH(100 SM) range ?
  • HF: Sky localization range (BNS, 20 deg^2) ?
  • BB: BNS range + BBH(30 SM?) range ? How to assign the weights ?
• Silicon option and suggestion from Australian group (Somiya)
• Publication plan ?
  • After the approval of white paper in the next f2f in August, we may want to publish a KAGRA-all paper to express our intention of the future plans to the GW and near-by communities, which I hope to assist to increase the probability of our funding request to be approved.
  • Summary of science cases
  • Sensitivities for O5 and beyond
• Conferences
  • GWADW (any news other than already shared by e-mail ?)

  • KIW6, June/21-23 - A.Nishizawa(science review including O3,O4,O5) and S.Haino(FPC overview and white paper)

  • Amaldi conference (Valencia), July/7-12 - Y.Michimura, (and H.Shinkai for KAGRA status talk)
