Gravitational Wave

The Gravitational Wave SIG will advocate for the new field of gravitational wave astronomy. GW SIG will 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 GW SIG is open to the scientific community.

About GW SIG

Advancing the New Field of Gravitational Wave Astronomy

The Gravitational Wave Science Interest Group (GW SIG) will provide quantitative metrics and assessments to NASA in preparation for a future gravitational wave mission. 

GW SIG will track and analyze evolving science goals and requirements, and will aid efforts to analyze technology development and prioritization plans as science goals are defined and mission concepts evolve within the PhysPAG portfolio. GW SIG will also support mission studies and concept development for future space-based gravitational wave observatories, including when cost savings are sought, or when new classes of sources are under consideration.

The collision of two black holes holes—a tremendously powerful event detected for the first time ever by the Laser Interferometer Gravitational-Wave Observatory, or LIGO—is seen in this still from a computer simulation. LIGO detected gravitational waves, or ripples in space and time generated as the black holes spiraled in toward each other, collided, and merged. This simulation shows how the merger would appear to our eyes if we could somehow travel in a spaceship for a closer look. It was created by solving equations from Albert Einstein's general theory of relativity using the LIGO data.
