论文摘要
我们表明，最近的Nanograv结果可以解释为与高振幅曲率扰动形成原始黑洞相关的随机重力波信号。重力波谱的指示振幅和功率与超级质量黑洞的原始种子形成非常吻合。
We show that the recent NANOGrav result can be interpreted as a stochastic gravitational wave signal associated to formation of primordial black holes from high-amplitude curvature perturbations. The indicated amplitude and power of the gravitational wave spectrum agrees well with formation of primordial seeds for supermassive black holes.
