我们报告了一个紧凑的二进制合并的观察，涉及一个22.2-24.3 M-圆点黑洞和一个紧凑的对象与质量为2.50-2.67 M-圆点（所有测量引用在90%的可信水平）。引力波信号GW 190814是在2019年8月14日21：10：39 UTC的LIGO和Virgo的第三次观测运行期间观测到的，在三探测器网络中的信噪比为25。该源位于18.5度（2），距离241（-41）（+45）Mpc;迄今为止还没有电磁对应物被证实。该源具有迄今为止用引力波测量的最不相等的质量比，0.112（-0.009）（+0.008），它的次要成分是在双致密物体系统中发现的最轻的黑洞或最重的中子星星。主黑洞的无量纲自旋被严格限制在
We report the observation of a compact binary coalescence involving a 22.2-24.3 M-circle dot black hole and a compact object with a mass of 2.50-2.67 M-circle dot (all measurements quoted at the 90% credible level). The gravitational-wave signal, GW190814, was observed during LIGO's and Virgo's third observing run on 2019 August 14 at 21:10:39 UTC and has a signal-to-noise ratio of 25 in the three-detector network. The source was localized to 18.5 deg(2) at a distance of 241(-41)(+45) Mpc; no electromagnetic counterpart has been confirmed to date. The source has the most unequal mass ratio yet measured with gravitational waves, 0.112(-0.009)(+0.008), and its secondary component is either the lightest black hole or the heaviest neutron star ever discovered in a double compact-object system. The dimensionless spin of the primary black hole is tightly constrained to
