COrE / PRISM workshop for a M4 ESA mission

10 févr. 2014, 09:00 → 11 févr. 2014, 16:30 Europe/Paris

Amphi de l'école d'architecture/APC (Laboratoire Astroparticule et Cosmologie (APC))

The aim of the COrE/PRISM workshop is to discuss and organize the preparation of a CMB polarization satellite mission proposal, to be submitted in response to the upcoming ESA call for M-class mission concepts (M4).

The workshop will focus primarily on key questions to define our next proposed mission:

- What value of r do we target?
- What science besides B-modes do we target?
- What is the impact of the science goals on the mission and instrument(s)?
- What should be our polarization modulation strategy?
- Should we propose an ancillary calibration spacecraft?

- What is feasible within the budget?

Participants are welcome to propose topics for discussion as well as submit short talks. Please send suggestions, comments, or proposals for contributed talks by email to Martin Bucher (bucher@apc.univ-paris7.fr) and Jacques Delabrouille (delabrouille@apc.univ-paris7.fr) with the following shared account in copy (paris.bmodes.2012@gmail.com).

Local Organising Committee: Martin Bucher, Jacques Delabrouille, Yannick Giraud-Héraud, Michel Piat, Matthieu Roman, Radek Stompor, Sarodia Vydelingum
