论文摘要

恒星簇是恒星反馈和宿主银河特性独特的示踪剂的基本单位。在这篇综述中,我们将首先关注他们的成分,即对他们的恒星种群及其周围的电离,温暖,中性和分子气体的详细见解。然后,我们超越本地群体,在各种进化阶段以及在当地宇宙中可访问的多种银河环境条件下审查星团群体。在高红移时,簇形成和进化的条件更加极端,我们只能观察到少数几个物体的综合光,我们认为我们将成为球形簇。因此,我们讨论了由当地宇宙中簇种群观察到的特性所告知的数值和分析方法,用于开发复杂的模拟,可能能够消除由球形群集种群携带的星系形成和组装的遗传图。

Star clusters are fundamental units of stellar feedback and unique tracers of their host galactic properties. In this review, we will first focus on their constituents, i.e.\ detailed insight into their stellar populations and their surrounding ionised, warm, neutral, and molecular gas. We, then, move beyond the Local Group to review star cluster populations at various evolutionary stages, and in diverse galactic environmental conditions accessible in the local Universe. At high redshift, where conditions for cluster formation and evolution are more extreme, we are only able to observe the integrated light of a handful of objects that we believe will become globular clusters. We therefore discuss how numerical and analytical methods, informed by the observed properties of cluster populations in the local Universe, are used to develop sophisticated simulations potentially capable of disentangling the genetic map of galaxy formation and assembly that is carried by globular cluster populations.
