In 1999, GWIC accepted a proposal from the Particle and Nuclear Astrophysics and Gravitation International Committee (PaNAGIC) to become a sub-panel of PaNAGIC. This connection is important because it gives GWIC its standing with IUPAP and the International Society on General Relativity and Gravitation.
Each year, GWIC provides a short report of its activities to PaNAGIC, which is incorporated into PaNAGIC's annual report to IUPAP. An archive of these reports is given below.
