LIGO-G050552-00-Z
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 pipelineo Scientific output of LIGO is ramping upo 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
designo There will be time for one or more additional long observationso 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
discoveryo 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
