First upper limits from LIGO on gravitational wave bursts
We report on a search for gravitational wave bursts using data from the first science run of the LIGO detectors. We focus on bursts with durations ranging from 4 msec to 100 msec, and with significant power in the LIGO sensitivity band of 150 to 3000 Hz. We bound the rate for such detected bursts at less than 1.6 events per day at 90% confidence level. This result is interpreted in terms of the...
متن کاملSearching for Gravitational-Wave Bursts with LIGO
We present recent results from searches by the LIGO Science Collaboration for bursts of gravitational-wave radiation, as well as the status of other ongoing searches. These include directed searches for bursts associated with observed sources (gamma-ray bursts, soft gamma repeaters) and untriggered searches for bursts from unknown sources. We also present the status of some newer investigations...
متن کاملImproved upper limits on the stochastic gravitational-wave background from 2009-2010 LIGO and Virgo data.
Gravitational waves from a variety of sources are predicted to superpose to create a stochastic background. This background is expected to contain unique information from throughout the history of the Universe that is unavailable through standard electromagnetic observations, making its study of fundamental importance to understanding the evolution of the Universe. We carry out a search for the...

We report the results of the first joint search for gravitational waves by the TAMA and LIGO collaborations. We looked for millisecond-scale unmodelled gravitational-wave bursts in 473hr of coincident data collected during early 2003. No candidate signals were found. We set an upper limit of 0.12 events per day on the rate of gravitational-wave transients, at 90% confidence level. Using simulat...
متن کاملFirst joint search for gravitational-wave bursts in LIGO and GEO 600 data
We present the results of the first joint search for gravitational-wave bursts by the LIGO and GEO 600 detectors. We search for bursts with characteristic central frequencies in the band 768–2048 Hz in the data acquired between 22 February and 23 March, 2005 (fourth LSC Science Run–S4). We discuss the inclusion of the GEO 600 data in the Waveburst–CorrPower pipeline that first searches for coin...
