论文摘要
2019年5月21日，Advanced Ligo和高级处女座探测器观察到重力波瞬态GW190521，这是迄今为止最重的二进制黑洞合并，迄今为止检测到的残余质量为142 $ \，$ M $ _ \ odot $。该观察结果是中间质量黑洞存在的第一个有力证据。该观察结果的重要性由相干波爆（CWB） - 搜索算法确定，该算法确定了GW190521，其源模型的假设最少。在本文中，我们演示了CWB在不使用信号模板的情况下检测二进制黑洞的能力，描述GW190521检测的细节，并确定CWB与二进制黑洞的理论波形模型的GW190521对GW190521对GW190521进行模型反应重建的一致性。
On May 21, 2019 Advanced LIGO and Advanced Virgo detectors observed a gravitational-wave transient GW190521, the heaviest binary black-hole merger detected to date with the remnant mass of 142$\,$M$_\odot$ that was published recently. This observation is the first strong evidence for the existence of intermediate-mass black holes. The significance of this observation was determined by the coherent WaveBurst (cWB) - search algorithm, which identified GW190521 with minimal assumptions on its source model. In this paper, we demonstrate the capabilities of cWB to detect binary black holes without use of the signal templates, describe the details of the GW190521 detection and establish the consistency of the model-agnostic reconstruction of GW190521 by cWB with the theoretical waveform model of a binary black hole.
