论文摘要
高级LIGO的重力波（GW）数据的分析提供了每个二进制黑洞的质量作为GWS的来源。与GW的二进制黑洞相对应的事件的质量超过$ 20 $ m $ _ \ odot $，它比X射线观察结果检测到的大量天体物理黑洞大得多。在这项工作中，我们将原始黑洞（PBH）视为Ligo事件的来源。假设暗物质的$ 100 \％$是由PBH制成的，我们估计这些物体制造二进制，合并和生产GWS的速率是RedShift的函数。 PBHS对GWS的重力镜头也可以增强菌株的幅度。我们模拟了由二进制PBHS提出的GWS，利文斯顿和汉福德探测器的检测阈值$ s/n> 10 $。对于PBHS的对数正态质量函数，我们生成事件的预期分布，将我们的结果与观察到的事件进行比较，并找到质量函数参数的最佳值（即$ M_C = 25 m_ \ odot $和$σ= 0.6 $）在对数正态质量函数中。将预期的事件数量与观察到的事件数量进行比较，排除了当前的二进制二进制形成PBH方案，这是Ligo检测到的GW事件源的候选者。
The analysis of gravitational Wave (GW) data from advanced LIGO provides the mass of each companion of binary black holes as the source of GWs. The mass of events corresponding to the binary black holes from GW is above $20$ M$_\odot$ which is much larger than the mass of astrophysical black holes detected by x-ray observations. In this work, we examine primordial black holes (PBHs) as the source of LIGO events. Assuming that $100\%$ of the dark matter is made of PBHs, we estimate the rate at which these objects make binaries, merge, and produce GWs as a function of redshift. The gravitational lensing of GWs by PBHs can also enhance the amplitude of the strain. We simulate GWs sourced by binary PBHs, with the detection threshold of $S/N>10$ for both Livingston and Hanford detectors. For the log-normal mass function of PBHs, we generate the expected distribution of events, compare our results with the observed events, and find the best value of the mass function parameters (i.e., $M_c =25 M_\odot$ and $σ=0.6$) in the log-normal mass function. Comparing the expected number of events with the number of observed ones rules out the present-Universe binary formation PBH scenario as the candidate for the source of GW events detected by LIGO.
