=== Isabel Leonor - searches for unmodeled GWs in coincidence with GRB === - get trigger time, search on 180 s segment surrounding trigger - compute cross-correlation in windows, look for largest - compare with off-source cross-correlations to establish significance - results consistent with null hypothesis === Richard O'Shaughnessy - probability of detecting CBCs with enhanced LIGO === - models for isolated binary evolution; changes in parameters affect results - also convolve with star-formation history of the Universe - systematics: simulations with few binaries - current estimate for enhanced LIGO: 0.34/yr (not including globular clusters) === Romain Gouaty - detection-confidence tests for CBC candidates === - nonstationarity produces accidental coincidence triggers (background) - detection checklist - check figures of merit (state vector, inspiral range); e.g., candidate happens which range is dropping - data quality flags, scimon/operator comments - statistical significance - check for transients in auxiliary group - candidate appearance in Qscans, SNR and chi^2 time series - look for correlation between H1 and H2 - this checklist is being automated, and Virgo tests will be included soon === Thomas Cokelaer - parameter estimation of inspiralling compact binaries === - nonspinning compact binaries, inspiral-only, initial LIGO - restricted waveform, SPA, covariance matrix - tau0 = A0/eta M^(-5/3), tau3 = A3/eta M^(-2/3) - study parameter estimation at low SNRs with template-bank Monte Carlo - find match at SNR > 20 except for equal mass system, where ML estimation does 2x better at high SNR; matched if nonphysical (i.e. masses) tau3's included in search - MV: explained by biased-estimator limit === Jim Cordes - radio pulsar overview === - TF search techniques, acceleration parameters - time-domain searches, reveal sporadic searches - possible prompt radio burst from GRB recently detected (Nature Express Sep 2007) - 10^4 pulsars by 2020, 300 timed routines - connections with GW: radio discovered targets, transient sources, algorithms, vulnerability to budget cuts === Ben Owen - How photon astronomy affects searches for continuous gravitational waves === === Andrzej Królak - All sky search of NAUTILUS data for periodic gravitational wave signals === === Vladimir Dergachev - Broadband Search for Continuous-Wave Gravitation Radiation with LIGO ===
