Get Involved by Joining a Science Interest Group

A Science Interest Group (SIG) consists of members interested in a specific sub-field of Physics of the Cosmos science (e.g., gravitational waves, gamma rays, etc.). These groups typically meet regularly to discuss and share scientific results, analysis techniques, and scientific gaps, as well as the role of NASA in advancing that sub-field. SIGs may also identify the data and technology needs that can help advance scientific discovery in the sub-field. Missions, data, and technologies from across the entire NASA portfolio are often utilized by SIGs.

• Cosmic Ray & Neutrino (CRN SIG) (Chairs: Andrew Romero-Wolf and Athina Meli): Coordinate community activities and preparations for a future cosmic ray astronomy mission.
• Cosmic Structure (CoS SIG) (Chairs: Vera Gluscevic and Rebekah Hounsell): Coordinate community activities for future space activities concerning the nature of dark energy, dark matter, neutrinos, and tests of inflation, as well as astrophysical galaxy evolution.
• Gamma Ray (GR SIG) (Chairs: Justin Finke, Eric Burns, and Manel Errando): Coordinate community activities and preparations for a future gamma ray astronomy mission.
• Gravitational Wave (GW SIG) (Chairs: Chiara Mingarelli and Alessandra Corsi): Coordinate community activities and preparations for a future gravitational wave mission.
• Inflation Probe (IP SIG) (Chair: Roger O’Brient): Coordinate community activities and preparations for a future cosmic microwave background polarization mission.
• New Great Observatories (NGO SAG, Cross-PAG) (Chairs: Grant Tremblay, PhysCOS; Janice Lee, COPAG; and Ilaria Pascucci; ExoPAG)
• Time Domain and Multi-Messenger Astrophysics Science Interest Group (TDAMM SIG) (Chairs: Eric Burns, Rebekah Hounsell, Brad Cenko, and Ian Crossfield): Coordinate activities for Time Domain and Multi-Messenger Astrophysics (TDAMM), recommended in the Astro2020 Decadal Survey as the top-priority sustaining activity in space for the coming decade.
• X-ray (XR SIG) (Chairs: Grant Tremblay, David Pooley, Kristin Madsen, and Chien-Ting Chen): Coordinate community activities and preparations for a future X-ray astronomy mission.
