论文摘要
尽管有传统的思维，但大量的黑洞可能潜伏在矮星系中。在过去的十年之前，在巨型星系的核中发现了几乎所有巨大的黑洞，并且矮星系中存在巨大的黑洞存在很大争议。现在，越来越多的研究人员社区从事各种观察性研究和矮星系的理论模型进行了改造，该领域已经改变了。在这一领域的工作不仅对于对矮星系进化和反馈的整体理解不仅很重要，而且还可以告诉我们，早期宇宙中第一个大型黑洞的“种子”是如何形成的。从这个角度来看，我讨论了该领域的当前状态以及未来的前景。我还提供了有关附近矮星系人口统计学的新见解，这些人口统计数据可用于帮助约束黑洞职业/主动分数，这是质量和矮星系类型的函数。
Despite traditional thinking, an appreciable population of massive black holes may be lurking in dwarf galaxies. Prior to the last decade, nearly all massive black holes were found in the nuclei of giant galaxies and the existence of massive black holes in dwarf galaxies was highly controversial. The field has now been transformed with a growing community of researchers working on a variety of observational studies and theoretical models of dwarf galaxies hosting massive black holes. Work in this area is not only important for a holistic understanding of dwarf galaxy evolution and feedback, but it may just tell us how the first "seeds" of massive black holes formed in the early Universe. In this Perspective, I discuss the current state of the field as well as future prospects. I also present new insights on the demographics of nearby dwarf galaxies, which can be used to help constrain the black hole occupation/active fraction as a function of mass and dwarf galaxy type.
