论文摘要
从数十个太阳质量黑洞二进制的合并中发现引力波的检测导致对原始黑洞（PBHS）作为暗物质候选者的兴趣激增。我们旨在（相对）概述PBHS作为暗物质候选人的状态，大约2020年夏季。首先，我们回顾了早期宇宙中PBH的形成，主要集中在膨胀通过通货膨胀产生的大密度扰动而形成的PBH。然后，我们回顾当今PBH的各种当前和未来限制。最后，我们讨论了该领域的主要开放问题。
The detection of gravitational waves from mergers of tens of Solar mass black hole binaries has led to a surge in interest in Primordial Black Holes (PBHs) as a dark matter candidate. We aim to provide a (relatively) concise overview of the status of PBHs as a dark matter candidate, circa Summer 2020. First we review the formation of PBHs in the early Universe, focusing mainly on PBHs formed via the collapse of large density perturbations generated by inflation. Then we review the various current and future constraints on the present day abundance of PBHs. We conclude with a discussion of the key open questions in this field.
