'''GW170608'''是[[激光干涉引力波天文台]]（LIGO）于2017年6月8日02:01:16.49UTC探测到的一次[[重力波 (相對論)|引力波]]事件。它起源于[[雙黑洞|双黑洞]]并合，两个黑洞的质量分别为<math>12^{+7}_{-2}\,M_\odot</math> 和 <math>7^{+2}_{-2}\,M_\odot</math>。<ref name="APJ">{{cite journal ||last1=Abbott |first1=Benjamin P.|title=GW170608: Observation of a 19-solar-mass Binary Black Hole Coalescence|doi=10.3847/2041-8213/aa9f0c|arxiv=1711.05578|journal=[[The Astrophysical Journal Letters]]|volume=851|issue=2|date=18 December 2017}}</ref><ref name="Phys">{{cite news|title=LIGO and Virgo announce the detection of a black hole binary merger from June 8, 2017|url=https://phys.org/news/2017-11-ligo-virgo-black-hole-binary.html|date=16 November 2017|accessdate=2018-01-01|archive-date=2020-11-09|archive-url=https://web.archive.org/web/20201109041130/https://phys.org/news/2017-11-ligo-virgo-black-hole-binary.html|dead-url=no}}</ref><ref>{{Cite news|url=https://www.ligo.caltech.edu/news/ligo20171115|title=LIGO and Virgo announce the detection of a black hole binary merger from June 8, 2017|date=November 15, 2017|work=LIGO Lab {{!}} Caltech|accessdate=17 November 2017|archive-url=https://web.archive.org/web/20180109221702/https://www.ligo.caltech.edu/news/ligo20171115|archive-date=2018-01-09|dead-url=yes}}</ref> 并合形成的黑洞约为18个太阳质量， 约一个太阳质量以引力波辐射的形式传递出去。<ref>{{Cite web|url=https://phys.org/news/2017-11-ligo-virgo-black-hole-binary.html|title=LIGO and Virgo announce the detection of a black hole binary merger from June 8, 2017|accessdate=20 November 2017|date=November 16, 2017|archive-date=2020-11-09|archive-url=https://web.archive.org/web/20201109041130/https://phys.org/news/2017-11-ligo-virgo-black-hole-binary.html|dead-url=no}}</ref>

== 事件探测 ==
由于汉福德的设备在事件发生时正在进行特定频率的测试，这次的引力波信号不是通过自动化分析得到的。利文斯顿的探测器最初通过目视检查的触发器认证了信号。对汉福德数据的手工处理，显示了与利文斯顿一致的信号。随后的调查研究确定，当时汉福德设备进行的测试并没有影响从数据中恢复出信号。<ref name=GCN_170608>{{cite web
