Cosmic Structure Science Interest Group
The goal of the Cosmic Structure Interest Group (CoSSIG) 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 CoSSIG 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.
CoSSIG also provides a way to discuss and coordinate areas of overlapping interest with the other SIGs, e.g, the Inflation Probe SIG (IPSIG), in understanding the theoretical origins of inflation, complementary gravitational tests to those of interest in the Gravitational Wave SIG (GWSIG), and complementary cluster science with X-ray SIG (XRSIG).
The CoSSIG is open to all members of the community.

Following up on a Nov 2018 mission PI diversity workshop, the NASA Science Mission Directorate (SMD) is planning a number of exciting opportunities open to community participation, including a new website for potential PIs, pre-review mission panels to ensure diversity and reduce conflicts of interest, research proposal writing workshops at conferences and for PIs developing their first proposal, career development positions, and a presentation by SMD Associate Administrator Thomas H. Zurbuchen on proposal statistical analysis. Please see the Associate Administrator's full update here
16 May 2019
June 1 2019 is the deadline for filling and submitting the technology gap submission form. We encourage members of the community to identify such gaps between today's state-of-the-art and what will be needed for missions identified by the 2010 Decadal Survey, the 2018 Astrophysics Implementation Plan, and/or the 30-year Astrophysics Road Map. Please see the Astrophysics Division Technologists letter
for more details, including how to submit a gap.
25 March 2019
NASA HQ Astrophysics Division has created a task force to assess NASA's role in strategic optimization of Gravitational Wave Electromagnetic Counterpart (GW-EM) astrophysics. See the Terms of Reference
for more details.
1 February 2019
Dr Terri Brandt confirmed as PCOS Chief Scientist.
