6. LIGO-G050552-00-Z The LIGO Scientific Collaboration 500 scientists at 42 institutions 27 US & 15 international

7. LIGO-G050552-00-Z LIGO Laboratory at Caltech 7 Operated as a phased array: - Enhance detection confidence - Localize sources - Decompose the polarization of gravitational waves - External triggers from EM observatories Growing International Network of GW Interferometers VIRGO: 3km 2005 - 2006 AIGO: (?)km Proposed LIGO-LHO: 2km, 4km On-line LIGO-LLO: 4km On-line GEO: 0.6km On-line TAMA: 0.3km On-line LCGT: 3 km planned Orbiting observatories

8. LIGO-G050552-00-Z LIGO Laboratory at Caltech 8 LIGO is embarking on an exciting observational campaign! o We have honed our analysis methods on a series of science runs that have produced 9 (7 PRD + 2 PRL) published results to date (including accepted for publication) o More publications are in the pipeline o Scientific output of LIGO is ramping up o Advanced LIGO start expected for FY2008 OPPORTUNITIES for the Collaboration: o The upcoming S5 science run will provide at least 1 year of integrated science data at design o There will be time for one or more additional long observations o Operation in coincidence with other detectors to corroborate detections o Virgo (French-Italian 3km interferometer) o GEO600 (UK/German 600m interferometer - part of LSC) o Coordination with  -ray observatories (HETE 2, Swift) o Outreach and education, broader impact CHALLENGES for the Collaboration : o Maintaining the impetus of a 24x7 campaign of production analysis that will enable timely discovery o The LSC has embraced and is fully reliant on the NSF-supported grid computing model that needs to be operated 24x7 for the collaboration by the few institutions with expertise & resources - Tier 0/1/2 centers of the LIGO Data Grid
