2017 年 6 月 8 日 02:01:16.49 UTC，两台先进激光干涉仪引力波天文台探测器观测到了两个恒星质量黑洞合并产生的引力波 (GW) 信号，网络信噪比为 。 13. 该系统是迄今为止观测到的最轻的黑洞双星，其组成质量为 12(2)(+7) 个 M 圆点和 7(2)(+2) 个 M 圆点（90% 可信区间）。这些位于低质量 X 射线双星中测量的黑洞质量范围内，因此使我们能够将通过引力波探测到的黑洞与电磁观测进行比较。光源的光度距离为340(-140)(+140) Mpc，对应红移0.07(-0.03)(+0.03)。我们验证了信号波形与广义相对论的预测一致。
On 2017 June 8 at 02:01:16.49 UTC, a gravitational-wave (GW) signal from the merger of two stellar-mass black holes was observed by the two Advanced Laser Interferometer Gravitational-Wave Observatory detectors with a network signal-to-noise ratio of. 13. This system is the lightest black hole binary so far observed, with component masses of 12(2)(+7) M-circle dot and 7(2)(+2) M-circle dot (90% credible intervals). These lie in the range of measured black hole masses in low-mass X-ray binaries, thus allowing us to compare black holes detected through GWs with electromagnetic observations. The source's luminosity distance is 340(-140)(+140) Mpc, corresponding to redshift 0.07(-0.03)(+0.03). We verify that the signal waveform is consistent with the predictions of general relativity.
