我们提出了与154伽玛射线暴（GRB），在2009-2010年，在第六次LIGO科学运行和第二次和第三次处女座科学运行的卫星伽玛射线实验检测到的引力波的搜索结果。我们进行两个不同的搜索：一个模型搜索的合并，无论是两个中子星或中子星星和黑洞，和搜索通用的，未建模的引力波爆发。我们没有发现引力波对应物的证据，无论是在这个样本中的任何一个单独的伽玛射线暴或与人口作为一个整体。对于所有的伽玛暴，我们都给出了到起源伽玛暴距离的下限，假设在150 Hz时，引力波发射能量为10（-2）M圆点c（2），中位数为17 Mpc。对于短硬伽玛射线暴，我们把排斥距离上的二进制中子星星和中子-星星-黑洞的祖先，使用天体物理学动机的源参数的先验，中值为16 Mpc和28 Mpc，分别。这些距离限制，虽然显着大于搜索，没有伽玛射线暴卫星观测的帮助下，是不够大，以期望与伽玛射线暴的巧合。然而，将这些排除投射到将于2015年开始运行的Advanced LIGO和Virgo的灵敏度上，我们发现与GRB相关的引力波的探测将变得非常可能。
We present the results of a search for gravitational waves associated with 154 gamma-ray bursts (GRBs) that were detected by satellite-based gamma-ray experiments in 2009-2010, during the sixth LIGO science run and the second and third Virgo science runs. We perform two distinct searches: a modeled search for coalescences of either two neutron stars or a neutron star and black hole, and a search for generic, unmodeled gravitational-wave bursts. We find no evidence for gravitational-wave counterparts, either with any individual GRB in this sample or with the population as a whole. For all GRBs we place lower bounds on the distance to the progenitor, under the optimistic assumption of a gravitational-wave emission energy of 10(-2) M-circle dot c(2) at 150 Hz, with a median limit of 17 Mpc. For short-hard GRBs we place exclusion distances on binary neutron star and neutron-star-black-hole progenitors, using astrophysically motivated priors on the source parameters, with median values of 16 Mpc and 28 Mpc, respectively. These distance limits, while significantly larger than for a search that is not aided by GRB satellite observations, are not large enough to expect a coincidence with a GRB. However, projecting these exclusions to the sensitivities of Advanced LIGO and Virgo, which should begin operation in 2015, we find that the detection of gravitational waves associated with GRBs will become quite possible.
