与第一代探测器相比，先进LIGO和先进Virgo探测器的第一次观测运行具有显着的灵敏度改进，在不到两年的时间内通过引力波（GW）探测产生了令人难以置信的发现和重大天体物理学结果。第一个观测到的GW信号对应于两个恒星质量黑洞合并的最后时刻和它们最后的坠落。在第一次观察运行（O 1）期间，观察到GW 150914和GW 151226具有高置信度（> 5σ），而LVT 151012的显著性较低（1.7σ）[1-5]。在第二次观测运行（O2）期间，GW 170104和GW 170814（由三个LIGO和Virgo探测器同时探测到）证实了恒星质量黑洞合并的估计速率[6，7]。最后，
The first observing runs of the Advanced LIGO and Advanced Virgo detectors, with significant sensitivity improvements compared to the first generation detectors, yielded in less than two years incredible discoveries and major astrophysics results via gravitational wave (GW) detections. The first observed GW signals corresponded to the final moments of the coalescence of two stellar-mass black holes and their final plunge. GW150914 and GW151226 were observed with high confidence (> 5σ), while LVT151012 was identified with a lower significance (1.7σ)[1–5] during the first observing run (O1). During the second observing run (O2), GW170104 and GW170814 (which was detected simultaneously by the three LIGO and Virgo detectors) have confirmed the estimated rate of stellar-mass black hole mergers [6, 7]. Lastly,
