论文摘要
尽管通常认为暗物质是某种形式的基本粒子，但原始黑洞（PBH）也可以提供一些。但是，各种约束将可能的质量窗口限制为$ 10^{16} $ - $ 10^{17} \，$ g，$ 10^{20} $ - $ 10^{24} \，$ g和$ 10 $ - $ 10 $ - $ 10^{3} {3} \，m _ {\ odot} $。最后的可能性是有争议的，但鉴于Ligo/处女座最近发现黑洞合并的发现具有特别的兴趣。 PBHS可能会产生重要的后果并解决各种宇宙学结合，即使它们只有一小部分深色 - 强度密度。特别是，那些大于$ 10^{3} \，m _ {\ odot} $可以通过种子或泊松效应生成宇宙学结构，从而减轻与标准冷的深色 - 深色 - 物种相关的某些问题，并且足够大的PBH可以为人星层核中的超级杂物黑色热量提供种子。更外向的是，PBH蒸发的普朗克质量遗物或大于$ 10^{12} \，m _ {\ odot} $大于$ 10^{12} \的大型黑洞可能会提供有趣的深色组件。
Although the dark matter is usually assumed to be some form of elementary particle, primordial black holes (PBHs) could also provide some of it. However, various constraints restrict the possible mass windows to $10^{16}$ - $10^{17}\,$g, $10^{20}$ - $10^{24}\,$g and $10$ - $10^{3}\,M_{\odot}$. The last possibility is contentious but of special interest in view of the recent detection of black-hole mergers by LIGO/Virgo. PBHs might have important consequences and resolve various cosmological conundra even if they have only a small fraction of the dark-matter density. In particular, those larger than $10^{3}\,M_{\odot}$ could generate cosmological structures through the seed or Poisson effect, thereby alleviating some problems associated with the standard cold dark-matter scenario, and sufficiently large PBHs might provide seeds for the supermassive black holes in galactic nuclei. More exotically, the Planck-mass relics of PBH evaporations or stupendously large black holes bigger than $10^{12}\,M_{\odot}$ could provide an interesting dark component.
