论文摘要
我们提供了一个简单的论点，结合了微透镜和Lyman-$α$森林的约束，表明在形成时大量的恒星质量原始黑洞的大量空间聚类被排除在外。因此，不可能通过增强其初始聚类来逃避现有的约束，从而阻止恒星质量的原始黑洞成为暗物质的主要组成部分。
Combining constraints from microlensing and Lyman-$α$ forest, we provide a simple argument to show that large spatial clustering of stellar-mass primordial black holes at the time of formation, such as the one induced by the presence of large non-Gaussianities, is ruled out. Therefore, it is not possible to evade existing constraints preventing stellar-mass primordial black holes to be a dominant constituent of the dark matter by boosting their initial clustering.
