我们提出的搜索结果的引力波（GWs）与伽玛射线暴检测的高级激光干涉引力波天文台（LIGO）的第一次观测运行期间。我们没有发现任何证据的GW信号的41伽玛射线暴的LIGO数据可用足够的持续时间。对于所有的伽马射线暴，我们使用乐观的假设，即具有10（-2）M（圆点）c（2）的GWs，来确定到源的距离的下限。在16-500 Hz频带内发射，我们发现在150 Hz处的中值90%置信限为71 Mpc。对于19个短/硬伽马射线爆发的子集，我们把距离的下限与中位数90%的置信限为90 Mpc的二进制中子星星（BNS）聚结，和150和139 Mpc的中子星黑洞聚结与自旋对准的轨道角动量和在一个通用的配置，分别。这是GW搜索所达到的最高距离限制。我们还详细讨论了与GRB 150906 B相关的GW搜索结果，GRB 150906 B是由行星际网络定位在本地星系NGC 3313附近的事件，其光度距离为54 Mpc（z = 0.0124）。假设伽马射线发射是以99%的喷流半开角发射的。此外，我们排除这样的祖细胞的距离分别为102 Mpc和170 Mpc。
We present the results of the search for gravitational waves (GWs) associated with gamma-ray bursts detected during the first observing run of the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO). We find no evidence of a GW signal for any of the 41 gamma-ray bursts for which LIGO data are available with sufficient duration. For all gamma-ray bursts, we place lower bounds on the distance to the source using the optimistic assumption that GWs with an energy of 10(-2)M(circle dot)c(2). were emitted within the 16-500 Hz band, and we find a median 90% confidence limit of 71 Mpc at 150 Hz. For the subset of 19 short/hard gamma-ray bursts, we place lower bounds on distance with a median 90% confidence limit of 90 Mpc for binary neutron star (BNS) coalescences, and 150 and 139 Mpc for neutron star-black hole coalescences with spins aligned to the orbital angular momentum and in a generic configuration, respectively. These are the highest distance limits ever achieved by GW searches. We also discuss in detail the results of the search for GWs associated with GRB 150906B, an event that was localized by the InterPlanetary Network near the local galaxy NGC 3313, which is at a luminosity distance of 54 Mpc (z = 0.0124). Assuming the gamma-ray emission is beamed with a jet half-opening angle 99%. Further, we exclude such progenitors up to a distance of 102 Mpc and 170 Mpc, respectively.
