1 GWIC Gravitational Wave International Committee Report to PaNAGIC 9-Sept-03

2 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: July 03 Pisa; July 05 in Japan  GWDAW Workshop - Data Analysis (yearly - location rotates) »Gravitational Wave Data Analysis Workshop »Techniques in Data Analysis, Computing and Networking »Next Meeting: Dec 02 Japan: Dec 03 in Milwaukee  Aspen Meeting - Techniques (yearly - rotates Aspen / Europe) »Advanced Detector Workshop »Techniques for advanced detectors »Next Meeting: Winter 04 in Aspen ; Winter 05 Elba

3 World-wide gravitational wave network  GWIC is working with the gravitational wave projects toward developing an eventual worldwide network for gravitational wave detection. IGEC  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 data under an agreement coordinated through GWIC  They collaboratively searched for coincidental gravitational wave bursts in the Galaxy in control of false alarm/false dismissal probabilities to get, at > 95% confidence level, upper limits of 0.O2 M sun converted into gravitational waves at the Galactic Center distance.

4 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 recently posted on gr-qc). »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.  GWIC Meeting at Amaldi Meeting (July 03): »Create a working group on statistical methods for gravitational wave data analysis »Developing guidelines for presenting results leading to publications on new results

5 World-wide gravitational wave network  GWIC Meeting at Amaldi Meeting (July 03): »Create a working group on statistical methods for gravitational wave data analysis »Developing guidelines for presenting results leading to publications on new results  Elected a new GWIC chair for Massimo Cerdonio
