Joint LIGO and TAMA300 search for gravitational waves from inspiralling neutron star binaries

Abstract: We search for coincident gravitational wave signals from inspiralling neutron star binaries using LIGO and TAMA300 data taken during early 2003. Using a simple trigger exchange method, we perform an intercollaboration coincidence search during times when TAMA300 and only one of the LIGO sites were operational. We find no evidence of any gravitational wave signals. We place an observational upper limit on the rate of binary neutron star coalescence with component masses between 1 and 3M[sun] of 49 per year per … Show more

“…False alarms from non-Gaussian transients (glitches) triggering spinning templates had an adverse affect on previous attempts to include spin effects in searches [8]. To counter this problem we also include here a signal-based veto, the χ 2 -test [28,29] used in previous LIGO searches [7,[30][31][32][33][34][35][36][37][38][39]. This veto reduces the significance of glitchinduced triggers in the search, and thus greatly reduces the threshold on signal SNR that must be applied to achieve a desired false-alarm rate.…”

“…The interferometer operated without power recycling from 1999 to 2001, performing six [7]. These observations were coincident with the science runs of the LIGO detectors [8]. With those nine times of observation runs, more than 3000 h data in total were accumulated [9].…”

“…Comparisons with previous LIGO [16,17] and LIGO-TAMA [8] searches have already been shown graphically in figure 12. The LIGO-TAMA search targeted millisecond-duration signals with frequency content in the 700-2000 Hz frequency regime (i.e., partially overlapping the present search) and had a detection efficiency of at least 50% (90%) for signals with h rss greater than ∼2 × 10 −19 Hz −1/2 (10 −18 Hz −1/2 ).…”
