The goal of the Cosmic Structure Science Interest Group (CoS SIG) is to serve communities interested in utilizing measures of cosmic structure based on 3-dimensional spectroscopic and photometric surveys of galaxies, galaxy clusters, supernovae, and gravitational lensing. Science drivers for the SIG include understanding the nature of dark energy, dark matter, neutrinos, and tests of inflation, as well as astrophysical galaxy evolution, amongst others.

The CoS SIG will provide a way to collect, discuss and communicate to NASA community inputs on future missions including quantitative metrics and assessments and new issues as we move up to the 2020 Decadal. This includes:

  • Review and update mission science goals following current developments in the field,
  • Review and update information about and requirements on potential foreground contaminants and their removal,
  • Review and update requirements on and developments in control of systematic errors, and
  • Assess necessary technology developments and prioritize areas for increased technical emphasis.

CoS SIG also provides a way to discuss and coordinate areas of overlapping interest with the other SIGs, e.g, the Inflation Probe SIG (IP SIG), in understanding the theoretical origins of inflation, complementary gravitational tests to those of interest in the Gravitational Wave SIG (GW SIG), and complementary cluster science with X-ray SIG (XR SIG).

The CoS SIG is open to all members of the community.
