The available data on the chirp mass distribution of the black holes in the coalescing binaries in O1-O3 LIGO/Virgo runs are analyzed and compared with theoretical expectations based on the hypothesis that these black holes are primordial with log-normal mass spectrum. The inferred best-fit mass spectrum parameters, $M_0=17 M_\odot$ and $\gamma=0.9$, fall within the theoretically expected range and shows excellent agreement with observations. On the opposite, binary black hole models based on massive binary star evolution require additional adjustments to reproduce the observed chirp mass distribution.

关于聚结黑洞的质量分布

分析了 O1-O3 LIGO/Virgo 运行中聚结双星中黑洞啁啾质量分布的可用数据，并与基于这些黑洞是原始对数正态质谱的假设的理论预期进行比较。推断的最佳拟合质谱参数 $M_0=17 M_\odot$ 和 $\gamma=0.9$ 落在理论预期范围内，并且与观察结果非常吻合。相反，基于大质量双星演化的双黑洞模型需要额外的调整来重现观察到的啁啾质量分布。
