  1. Amaldi 5GWIC Report by B Barish, chair

  2. GWICgravitational wave international committee • International Union of Physics and Applied Physics (IUPAP) • 21 Commissions -- C4 Cosmic Rays • 2 Associated Commissions-- AC2 General Relativity • 3 Working Groups: ICFA; PaNAGIC and Women in Physics • Highest level international body of scientists internationally • “Particle and Nuclear Astrophysics and Gravitation International Committee” (PaNAGIC) • Working group attached to C4 • PaNAGIC Working groups: • GWIC • HENAP • Bi-Annual Meeting • TAUP - Sept 02 - Seattle

  3. International Conferences sponsored by GWIC • AMALDI Conference (odd years - location rotates world-wide) • Primary conference in gravitational-wave physics and detection • Terrestrial; Space; Theory; Sources; and Techniques • Next Conference: Summer 05 in Japan • GWDAW Workshop (yearly - location rotates) • Gravitational Wave Data Analysis Workshop • Techniques in Data Analysis, Computing and Networking • Next Meeting: Dec 03 in Milwaukee • Aspen Meeting (yearly - rotates Aspen / Europe) • Advanced Detector Workshop • Techniques for advanced detectors • Next Meeting: Winter 04 in Aspen ; Winter 05 Elba

  4. World-wide gravitational wave network • GWIC is working with the gravitational wave projects toward developing an eventual worldwide network for gravitational wave detection. • The 5 “bar” detectors:IGEC • ALLEGRO(NSF- Baton Rouge),AURIGA(INFN – LNL),EXPLORER(INFN-CERN),NAUTILUS(INFN- LNF),NIOBE(ARC- Perth)exchanged and analyzed their 1997-2000 data under an agreement coordinated through GWIC • GWIC is helping coordinate activities for gravitational wave detectors toward a grid computing environment • The grid distributed computing philosophy is well suited to a broad world-wide collaboration • Interfaces to existing software systems and tests are underway

  5. World-wide gravitational wave network • GWIC is helping with steps toward a world-wide network including the large interferometers. So far, bi-lateral exchanges • GEO - LIGO for the S1 data run (17 days Sept 02). Joint upper limits presented at this conference. Joint papers after the conference. • TAMA - LIGO exchange data for S2 data (60 days Spring 03). Small joint working group to coordinate the joint analysis. • Virgo and LIGO exchanging environmental data, and Virgo preparing for future gravitational data exchange. • Yesterday’s GWIC Meeting : • Create a working group on statistical methods for gravitational wave data analysis • Developing guidelines for presenting results leading to publications on new results

  6. GWIC • Elected a new GWIC chair for 2003-05 Massimo Cerdonio • On behalf of GWIC, I welcome all of you to Amaldi 5 and look forward to an exciting meeting.
