WG11: Gravitational Wave International Committee (GWIC)

Working Group 11 (WG11), the Gravitational Wave International Committee (GWIC) was created by the International Union of Pure and Applied Physics in 1997 to facilitate international collaboration and cooperation in the construction, operation and use of the major gravitational wave detection facilities world wide. GWIC is associated with IUPAP C19, AC2 and WG10.

Charge to Working Group

  • 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;
  • organise 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.
