  3. Agenda for today 0930 - 0945 Brief introductory remarks Albert Lazzarini, LIGO Laboratory Caltech 0945 - 1005 LIGO Status from the Collaboration Peter Saulson, Syracuse, LSC Spokesman 1005 - 1030 LIGO Science Nuggets - recent results Jolien Creighton, UW Milwaukee 1030 - 1045 Break 1045 - 1105 LIGO and Grid Activities Patrick Brady, UW Milwaukee 1105 - 1120 LIGO impact on the grid Scott Koranda, UW Milwaukee 1120 - 1140 LIGO broader impact and outreach Fred Raab, LIGO Hanford Observatory 1140 - 1200 Closing remarks & discussion Patrick Brady, UW Milwaukee LIGO Laboratory at Caltech

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!

  5. Interferometers are aligned along the great circle connecting the sites Hanford, WA MIT 3002 km (L/c = 10 ms) <- Livingston, LA Caltech Livingston, LA Hanford, WA -> The LIGO Observatories LIGO Laboratory at Caltech

  6. The LIGO Scientific Collaboration 500 scientists at 42 institutions27 US & 15 international

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

  8. 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
