摘要

背景星系的弱引力透镜提供了对星系团内部和周围投射物质分布的直接探测。在这里，我们提出了一个独立的教学回顾星系团星系弱透镜，涵盖了一系列主题相关的宇宙学和天体物理学的应用。我们从第一原理开始回顾引力透镜的理论基础，特别关注弱引力透镜的基础和先进技术。我们总结和讨论了最近在观测和理论基础上对星系团星系弱透镜研究的关键发现，重点是星系团质量分布、浓度-质量关系、溅射半径以及星系团宇宙学中广泛的质量校准工作的意义。

Cluster–galaxy weak lensing

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 a 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.

期刊介绍： The Astronomy and Astrophysics Review is a journal that covers all areas of astronomy and astrophysics. It includes subjects related to other fields such as laboratory or particle physics, cosmic ray physics, studies in the solar system, astrobiology, instrumentation, and computational and statistical methods with specific astronomical applications. The frequency of review articles depends on the level of activity in different areas. The journal focuses on publishing review articles that are scientifically rigorous and easily comprehensible. These articles serve as a valuable resource for scientists, students, researchers, and lecturers who want to explore new or unfamiliar fields. The journal is abstracted and indexed in various databases including the Astrophysics Data System (ADS), BFI List, CNKI, CNPIEC, Current Contents/Physical, Chemical and Earth Sciences, Dimensions, EBSCO Academic Search, EI Compendex, Japanese Science and Technology, and more.
