UMICH-2015: Cosmology with CMB-S4
Welcome to the wiki for the “Cosmology with CMB-S4” workshop at the University of Michigan September 21-22, 2015.
As highlighted in the workshop announcement, the goal of the workshop is to further develop the science goals, including the requisite measurements to achieve them, for the next generation ground-based Cosmic Microwave Background program, CMB-S4. The output of the workshop will lead to a working draft of the CMB-S4 “Science Book” as well as action items and goals for the next workshop.
This workshop is one of a series of dedicated meetings, roughly every 6 months. The plan for the U. Michigan workshop is not to provide the final science goals and instrument specifications/design, but rather to outline the science potential of CMB-S4 and the steps we need to take to determine the goals and instrumentation requirements., i.e., simulations, technological studies, etc.
With this in mind we have organized the workshop around highly interactive “break-out” sessions, the findings of which are then presented at a plenary session at the end of each day. The goal of these sessions is to encourage free-wheeling discussion of specific topics, which in addition to helping to draft the CMB-S4 science book, will also lead to collaborations and hopefully published results.
On the first day, there will be three parallel break-out sessions organized around the science themes of “Inflation”, “Dark Energy / Gravity / Dark Matter” and “Neutrino and Light Relativisic Species”.
On the second day there will be four break-out sessions organized around the tools and technique themes of “Instrumentation I”, Instrumentation II”, “CMB-Lensing” and “Computing / simulations and forecasting / analysis challenges”.
We want to encourage broad and lively interactions, so the break-out session themselves are broken into ~hour slots with long breaks between them to enable cross-theme discussions, switching sessions, etc.
Each break-out session theme has an overall coordinator, as well as a moderator (the session organizers). Each break-out session will begin with a few words from the session organizers to start the discussion. The organizers should develop a few ideas in sufficient detail to spark initial discussion. These need not be worked solutions, but rather a starting point for discussion and future work. All participants are encouraged to come to the break-out sessions armed with a few provocative ideas. We strongly encourage participants to provide input on this wiki and to contact the session organizers prior to the workshop to help ensure lively and productive discussion.
At the end of each day there will be a plenary session at which the “theme” coordinators present the discussions/findings/science reach and future steps. We have allowed time for the session organizers to put together these informal presentations. The hope is that the plenary sessions will be highly interactive, so feel free to be provocative.
About this wiki
We plan to use this WIKI to help organize the sessions, to capture the input from the sessions, to list next steps, and to help draft/outline the science book. An initial page stub is provided for each break-out session, including the title, coordinator and moderator (i.e., session organizers) , and perhaps a short list of topics, ideas for discussion. The session organizers are encouraged to flesh these pages out, including enlisting support from selected workshop participants, prior to the workshop. Each workshop participant will have read/write permission and is also encouraged to add to the wiki.
It is expected that the session organizers will use the wiki during the break-out sessions, and probably also for the plenary session. Participants are encouraged to edit the wiki directly, including uploading plots or a few slides.
