GRB触发的LIGO数据中引力波的搜索

GRB-triggered searches for gravitational waves in LIGO data

Alexander Dietz

摘要:

LIGO引力波探测器最近达到了设计灵敏度,并完成了为期两年的科学运行。在此期间,收集了一年的数据,其敏感性前所未有。我将简要描述LIGO探测器的状态和最近科学运行的整体质量。我还将介绍在2007年2月1日探测到的短伽马射线暴的引力波数据中寻找螺旋波形的结果,其天空位置误差框与M31的旋臂重叠。没有发现引力波信号,在99%的置信水平下可以排除M31中的双星合并。

英文摘要:

The LIGO gravitational wave detectors have recently reached their design sensitivity and finished a two-year science run. During this period one year of data with unprecedented sensitivity has been collected. I will briefly describe the status of the LIGO detectors and the overall quality of the most recent science run. I also will present results of a search for inspiral waveforms in gravitational wave data coincident with the short gamma ray burst detected on 1st February 2007, with its sky location error box overlapping a spiral arms of M31. No gravitational wave signals were detected and a binary merger in M31 can be excluded at the 99% confidence level.
