Radio CMB x-ray GW sky? sky? GRBs LISA band: 100 Hz < f < 10 mHz Adv. LIGO band: 10 Hz < f < 8 kHz The EM Window on the Universe New Window on Universe • GRAVITATIONAL WAVES WILL GIVE A NEW AND UNIQUE VIEW OF THE DYNAMICS OF THE UNIVERSE. • EXPECTED SOURCES: • BLACK HOLES, • SUPERNOVAE, PULSARS AND • COMPACT BINARY SYSTEMS • THE EARLY UNIVERSE • POSSIBILITY FOR THE UNEXPECTED IS VERY REAL!

LIGO is embarking on an exciting observational campaign! • 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) • More publications are in the pipeline • Scientific output of LIGO is ramping up • Advanced LIGO start expected for FY2008 • OPPORTUNITIES for the Collaboration: • The upcoming S5 science run will provide at least 1 year of integrated science data at design • There will be time for one or more additional long observations • Operation in coincidence with other detectors to corroborate detections • Virgo (French-Italian 3km interferometer) • GEO600 (UK/German 600m interferometer - part of LSC) • Coordination with -ray observatories (HETE 2, Swift) • Outreach and education, broader impact • CHALLENGES for the Collaboration : • Maintaining the impetus of a 24x7 campaign of production analysis that will enable timely discovery • 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 LIGO Laboratory at Caltech
