Gravitational Wave Science Interest Group

The goal of the Gravitational Wave Science Analysis Group (GWSIG) is to provide quantitative metrics and assessments to NASA in preparation for a future gravitational wave mission. Specifically, the GWSIG will:

  • Track and analyze evolving science goals and requirements, especially as our understanding of three standard sources of gravitational waves (supermassive black hole binaries, extreme mass ratio inspirals, galactic binaries) continues to improve.
  • Support mission studies and concept development for future space-based gravitational wave observatories, including when cost savings are sought, or new classes of sources are under consideration (such as the stochastic gravitational wave background from the inflationary epoch).
  • Aid efforts to analyze technology development and prioritization plans as science goals are defined and mission concepts evolve within the PhysPAG portfolio.
  • Advocate for the brand new field of gravitational wave astronomy, build a vibrant community of gravitational wave astronomers, and promote the discovery space in this new field to the wider scientific community and to the public.
  • The GWSIG is open to all members of the community.

    If you are interested in contributing to the work of the GWSIG, please subscribe using the link below. For other inquiries, e-mail co-chairs Sean McWilliams (West Virginia University) at sean.mcwilliams@mail.wvu.edu and Eric Burns (Louisiana State University) at erickayserburns@gmail.com.
