PhysPAG Science Interest Groups (SIGs)

Science Interest Groups (SIGs) are standing groups of scientists with interests in a certain area of astrophysics. SIGs provide quantitative metrics and assessments to NASA in regard to current and future needs of the community in that area, and act as a focal point and forum for the community.

Most SIGs operate within one of the three themes of NASA Astrophysics — Physics of the Cosmos, Cosmic Origins, and Exoplanet Exploration — but some encompass all astrophysics themes.

All PhysCOS SIGs are chaired by one or more members of the PhysPAG Executive Committee. Anyone subscribed to a SIG’s mailing list is considered a member of the SIG.

  • Cosmic Ray (CR 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 or GammaSIG) (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.

  • 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.

  • JAXA, NASA XRISM Mission Ready for Liftoff

    XRISM launched successfully on Wednesday, Sept. 6, 2023, at 7:42 p.m. EDT (Thursday, Sept. 7, 8:42 a.m. in Japan). The spacecraft separated from the rocket at 7:56 p.m. EDT.Read more.
