论文摘要
作为与Ligo/处女座检测到的二进制黑洞（BBH）合并事件结合的候选者，原始黑洞（PBHS）为研究小尺度上的原始曲率扰动提供了有用的工具。使用GWTC-1到GWTC-3目录，在PBHS源自通货膨胀时期的小尺度上的大型原始曲率扰动的情况下，我们首次重建了小尺度上原始曲率扰动的功率谱。发现原始功率谱的幅度的值将增强到$ \ \ \ natercal $ \ mathcal {o}（1）$ pc上的$ \ MATHCAL {O}（10^{ - 2}）$。这可能意味着PBH作为可能的BBH合并候选者的有效性。
As a candidate bound for the Binary Black Hole (BBH) merger events detected by LIGO/Virgo, Primordial Black Holes (PBHs) provide a useful tool to investigate the primordial curvature perturbations on small scales. Using the GWTC-1 to GWTC-3 catalogs, under the scenario that PBHs originate from large primordial curvature perturbations on small scales during inflationary epoch, we for the first time reconstruct the power spectrum of primordial curvature perturbations on small scales. It is found that the value of the amplitude of the primordial power spectrum is enhanced to $\mathcal{O}(10^{-2})$ on scales $\mathcal{O}(1)$ pc. This may imply the validity of PBH as a possible BBH merger candidate.
