Global coordination
for GW physics and astronomy

Since its formation in 1997, Gravitational Wave International Committee (GWIC) has facilitated international collaboration and cooperation in the construction, operation and use of the major gravitational wave detection facilities world-wide. It is associated with the International Union of Pure and Applied Physics (IUPAP) as its Working Group WG.11. Through this association, GWIC is connected with the International Society on General Relativity and Gravitation (IUPAP's Affiliated Commission AC.2), its Commission C19 (Astrophysics), and another Working Group, the AstroParticle Physics International Committee (APPIC).


Promote international cooperation in all phases of construction and scientific exploitation of gravitational-wave detectors

Coordinate and support long-range planning for new instrument proposals, or proposals for instrument upgrades

Promote the development of gravitational-wave detection as an astronomical tool, exploiting especially the potential for multi-messenger astrophysics

Organize regular, world-inclusive meetings and workshops for the study of problems related to the development and exploitation of new or enhanced gravitational-wave detectors, and foster research and development of new technology

Represent the gravitational-wave detection community internationally, acting as its advocate

Provide a forum for project leaders to regularly meet, discuss, and jointly plan the operations and direction of their detectors and experimental gravitational-wave physics generally

GWIC Roadmap

In the coming decades, ultra-sensitive arrays of ground-based instruments and complementary spaced-based instruments will continue to observe the gravitational wave sky, inevitably discovering entirely unexpected phenomena while providing new insight into many of the most profound astrophysical phenomena known. This new window into the cosmos could revolutionize humanity’s understanding of the Universe in which we live.

The goal of this roadmap is to serve the international gravitational wave community and its stakeholders as a tool for the development of capabilities and facilities needed to address the exciting scientific opportunities on the intermediate and long-term horizons.

This roadmap will serve the international gravitational wave community and its stakeholders as a strategic tool in planning for the development of capabilities and facilities needed to seize the tremendous scientific opportunities now on the horizon. This material represents the consensus best judgment of GWIC following discussions with leaders in the gravitational-wave field and with other members of the gravitational physics and astrophysics communities, and with representatives of funding agencies.
