Science Interest Group
Cosmic Structure
The Cosmic Structure SIG (CoS SIG) will serve as a focal point and forum for the cosmic structure community and will coordinate with other SIGs in areas of overlapping interest. The Cosmic Structure SIG is open to the scientific community.
About CoS SIG
Studying the Nature of Dark Energy, Dark Matter, Neutrinos, Inflation, and Galactic Evolution
The Cosmic Structure Science Interest Group (CoS SIG) will 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 Cosmic Structure SIG will collect, discuss, and communicate to NASA our community input, including quantitative metrics and assessments, with regard to current and future missions for exploring the structure of the cosmos.
