伽马射线暴(γ-ray Burst，GRB)是一种强烈的伽马射线闪光，大约每天发生一次，在天空中呈各向同性分布(例如，见Mészáros 2006及其参考文献)。在短至一毫秒的时间尺度上爆发的可变性表明，源是非常紧凑的，而对宿主星系的识别和对100多个爆发的红移的测量表明，伽玛暴来自河外。1993年；Gehreles等人。2006)。大多数短伽玛暴(≲2 S，具有硬光谱)的前身被广泛认为是中子星双星或中子星黑洞双星的合并；例如参见Nakar(2007年)、柴田和谷口(2008年)、Liu等人(2008年)、Anderson等人(2008年)和Etienne等人(2009年)。一小部分(高达≃15%)的短时伽马暴也被认为是由于局部分布的软伽马中继器产生的巨大耀斑(SGRS；Duncan&Thompson 1992；Tanvir等人)。2005年；Nakar等人。2006年；Chapman等人。2009年)。另一方面，长伽玛暴(≳2 S，具有软光谱)与核心塌缩超新星有关(加拉马等人)。1998年；Hjorth等人。2003年；Malesani等人。2004年；Campana等人。2006)。合并和超新星情景都导致形成恒星质量的黑洞和吸积盘(Fryer等人。1999年；Cannizzo&Gehrels2009)，在这一过程中预计会发射引力辐射。到目前为止，已经使用LIGO或处女座的数据对与伽玛暴有关的引力波爆发(GWB)进行了多次搜索。第二次LIGO科学运行的数据被用来搜索来自GRB030329/SN 2003dh的引力波信号(Abbott等人)。2005)，一颗明亮的伽玛暴及其伴生的超新星位于z=0的红移。1685年。随后搜索了在第二、第三和第四次LIGO科学运行期间发现的与39个伽玛暴一致的GWB(Abbott等人)。2008b)。来自Virgo探测器的数据用于搜索与GRB 050915a相关的GWB(Acernese等人。2007、2008a)。最近，对来自第五次LIGO科学运行的数据进行了分析，以搜索来自GRB 070201的GWB或二元结合激发信号(Abbott等人。2008a)。这个短时伽玛暴有一个与仙女座星系(M31)重叠的位置误差盒，距离为770kpc。在这些搜索中没有发现引力波信号的证据。在伽马射线暴070201的情况下，没有探测到相关的引力波提供了关于它的祖先的重要信息，高度可信地排除了M31中的致密天体双星。在这篇文章中，我们介绍了在第五次LIGO科学运行(S5)和第一次处女座科学运行(VSR1)期间，通过基于卫星的伽马射线实验探测到的与137个伽玛暴相关的GWB的结果，这两个科学运行总共跨越了
Gamma-ray bursts (GRBs) are intense flashes of γ-rays which occur approximately once per day and are isotropically distributed over the sky (see, eg, Mészáros 2006, and references therein). The variability of the bursts on timescales as short as a millisecond indicates that the sources are very compact, while the identification of host galaxies and the measurement of redshifts for more than 100 bursts have shown that GRBs are of extragalactic origin.GRBs are grouped into two broad classes by their characteristic duration and spectral hardness (Kouveliotou et al. 1993; Gehrels et al. 2006). The progenitors of most short GRBs (≲ 2 s, with hard spectra) are widely thought to be mergers of neutron-star binaries or neutron-star-black-hole binaries; see, for example, Nakar (2007), Shibata & Taniguchi (2008), Liu et al.(2008), Anderson et al.(2008), and Etienne et al.(2009). A small fraction (up to≃ 15%) of short-duration GRBs are also thought to be due to giant flares from a local distribution of soft-gamma repeaters (SGRs; Duncan & Thompson 1992; Tanvir et al. 2005; Nakar et al. 2006; Chapman et al. 2009). Long GRBs (≳ 2 s, with soft spectra), on the other hand, are associated with core-collapse supernovae (Galama et al. 1998; Hjorth et al. 2003; Malesani et al. 2004; Campana et al. 2006). Both the merger and supernova scenarios result in the formation of a stellar-mass black hole with accretion disk (Fryer et al. 1999; Cannizzo & Gehrels 2009), and the emission of gravitational radiation is expected in this process. To date, several searches for gravitational-wave bursts (GWBs) associated with GRBs have been performed using data from LIGO or Virgo. Data from the second LIGO science run were used to search for a gravitational-wave signal from GRB 030329/SN 2003dh (Abbott et al. 2005), a bright GRB and associated supernova located at a redshift of z= 0. 1685. This was followed by a search for GWBs coincident with 39 GRBs which were detected during the second, third, and fourth LIGO science runs (Abbott et al. 2008b). Data from the Virgo detector were used to search for a GWB associated with GRB 050915a (Acernese et al. 2007, 2008a). Most recently, data from the fifth LIGO science run were analyzed to search for a GWB or binary coalescence inspiral signal from GRB 070201 (Abbott et al. 2008a). This short-duration GRB had a position error box overlapping the Andromeda galaxy (M31), located at a distance of 770 kpc. No evidence for a gravitational-wave signal was found in these searches. In the case of GRB 070201, the nondetection of associated gravitational waves provided important information about its progenitor, ruling out a compact-object binary in M31 with high confidence. In this paper, we present the results of a search for GWBs associated with 137 GRBs that were detected by satellite-based gamma-ray experiments during the fifth LIGO science run (S5) and first Virgo science run (VSR1), which collectively spanned
