Welcome to the wiki for the Cosmology with CMB-S4 workshop at SLAC National Accelerator Laboratory, February 27-March 1, 2017.

Official Workshop Website: Venue, Participants, Hotels, Logistics.

Workshop overview

SLAC-2017 continues a successful series of workshops bringing together the CMB community to plan a coordinated, stage-4 ground-based CMB experiment.

Themes of this workshop include a particular focus on

  • Clusters and high-ell science
  • Systems engineering and technical flowdown
  • Discussion of the structure of a formal CMB-S4 scientific collaboration.

The first two days of the workshop are a formal program (agenda below), plus a splinter meeting on the third day.

About this wiki

As for the previous two workshops, we will use this wiki to organize the sessions and to capture the input from the sessions, and develop next steps. Initial page stubs will be provided for each break-out session. The wiki will be used during the break-out sessions, and also for the plenary session. Participants are encouraged to edit the wiki directly, including uploading plots or a few slides.
