论文摘要
背景星系的弱重力镜头可直接探测星系簇内外的预测物质分布。在这里，我们提出了群集的独立教学综述 - galaxy弱镜头，涵盖了与其宇宙学和天体物理应用相关的一系列主题。我们首先回顾了第一原理引力镜头的理论基础，并特别注意弱重力镜头的基础和先进技术。我们总结并讨论了最近群集的关键发现 - 关于观察和理论基础的galaxy弱透镜研究，重点是集群质量谱，浓度 - 质量关系，飞溅半径以及对集群宇宙学的广泛质量校准工作的影响。
Weak gravitational lensing of background galaxies provides a direct probe of the projected matter distribution in and around galaxy clusters. Here we present a self-contained pedagogical review of cluster--galaxy weak lensing, covering a range of topics relevant to its cosmological and astrophysical applications. We begin by reviewing the theoretical foundations of gravitational lensing from first principles, with special attention to the basics and advanced techniques of weak gravitational lensing. We summarize and discuss key findings from recent cluster--galaxy weak-lensing studies on both observational and theoretical grounds, with a focus on cluster mass profiles, the concentration--mass relation, the splashback radius, and implications from extensive mass calibration efforts for cluster cosmology.
