We present a formalism for calculating the probability distribution of the most massive primordial black holes (PBHs) expected within an observational volume. We show how current observational upper bounds on the fraction of PBHs in dark matter translate to constraints on extreme masses of primordial black holes. We demonstrate the power of our formalism via a case study, and argue that our formalism can be used to produce extreme-value distributions for a wide range of PBH formation theories.

极端原始黑洞

我们提出了一种计算在观测体积内预期的最大质量原始黑洞 (PBH) 的概率分布的形式。我们展示了暗物质中 PBH 分数的当前观测上限如何转化为对极端原始黑洞质量的限制。我们通过案例研究证明了我们的形式主义的力量,并认为我们的形式主义可用于为广泛的 PBH 形成理论产生极值分布。
