论文摘要
分析了O1-O3 Ligo/处女座运行中合并黑洞二进制的CHIRP质量分布的可用数据，并在统计上与基于这些黑洞具有原始质量质量光谱的原始的假设计算的分布进行了统计比较。理论上计算出的CHIRP质量分布，具有推断最佳可接受的质谱参数，$ m_0 = 17 m_ \ odot $和$γ= 0.9 $，完美地描述了数据。 $ m_0 $的值非常符合理论上的预期。在相反的情况下，黑洞二进制文件的CHIRP质量分布起源于巨大的二进制恒星进化，需要进行其他模型调整以重现观察到的Chirp质量分布
Available data on the chirp mass distribution of the coalescing black hole binaries in O1-O3 LIGO/Virgo runs are analyzed and compared statistically with the distribution calculated under the assumption that these black holes are primordial with a log-normal mass spectrum. The theoretically calculated chirp mass distribution with the inferred best acceptable mass spectrum parameters, $M_0=17 M_\odot$ and $γ=0.9$, perfectly describes the data. The value of $M_0$ very well agrees with the theoretically expected one. On the opposite, the chirp mass distribution of black hole binaries originated from massive binary star evolution requires additional model adjustments to reproduce the observed chirp mass distribution
