UMICH-2015: Dark Energy / Gravity / Dark Matter
From CMB-S4 wikiJump to navigationJump to search
Co-Coordinators: Bill Holzapfel & Wayne Hu
- Explore the interplay between methods, models, and metrics in defining CMB S4 modality for these dark materials
Moderators and Goals:
- break-out session 1: Rob Caldwell
- What CMB S4 observations can be used to distinguish mechanisms of cosmic acceleration?
- What observations can be used to falsify a cosmological constant?
- What are the complementary probes?
- break-out session 2: Brad Benson
- What are the cosmological constraints on dark energy, modified gravity, and neutrinos from a CMB-S4 SZ cluster survey?
- What synergies will there be with other multi-wavelength surveys?
- How many clusters (vs mass and redshift) will CMB-S4 detect? How will this vary with specs and foregrounds?
- How well can we calibrate cluster masses and with which techniques?
- break-out session 3: Francesco de Bernardis & Cora Dvorkin
- Which kSZ measurements are realistic? How to implement proper forecasts?
- What parameters space should be explored with kSZ?
- How do kSZ probes compare to others in terms of constraints?
- How do forecasts on Dark Matter annihilation change when including foregrounds?
- How much can we tighten the constraints on <sigma v>/m by adding prior information?
- What other dark matter scenarios can we learn about from the CMB? (baryon/dark matter interactions, a complex dark sector, dark matter scattering with neutrinos...)
