AI 中文总结
该综述系列第一部分聚焦星系熄灭的观测研究，梳理了近二十年多类观测设备与巡天的进展，探讨了星系熄灭的相关问题、识别途径及高红移前沿的最新观测结果。
AI 中文摘要
本综述系列文章的目标是从观测和理论视角全面概述星系的恒星形成与熄灭过程。基于大量文献，我们试图回答一个看似简单却极具挑战性的问题：为何星系会停止形成恒星？在第一部分中，我们聚焦于观测结果，尤其是近二十年来在解答这一基础问题上取得的巨大进展；第二部分则侧重理论与模拟，包括对其直接观测检验的讨论。观测方面，大视场星系光谱巡天、空间分辨光谱学、高分辨率亚毫米与射电观测、X射线观测、哈勃空间望远镜（HST）以及最新的詹姆斯·韦布空间望远镜（JWST）的出现，均极大推动了我们对恒星形成及其在星系熄灭过程中终止的实证认知。我们探讨了熄灭旨在解决的基础问题、观测中识别宁静星系的各类途径、星系群研究对熄灭的观测限制，以及熄灭的空间分辨视角。本部分综述最后，详细讨论了JWST观测获得的高红移前沿星系熄灭的最新结果。
英文摘要
The goal of this review article series is to provide a comprehensive overview of galactic star formation and quenching from both an observational and theoretical perspective. Drawing on a vast quantity of literature, we attempt to answer a deceptively simple question: why do galaxies cease forming stars? In Part I, we concentrate on observational results, especially from the past two decades, where there have been enormous advances made towards answering this fundamental question. In Part II we focus on theory and simulations, including discussion of direct observational tests thereof. Observationally, the advent of wide-field spectroscopic galaxy surveys, spatially resolved spectroscopy, high resolution sub-mm and radio observations, X-ray observations, the Hubble Space Telescope (HST), and most recently the James Webb Space Telescope (JWST) have all contributed significantly to our empirical knowledge of star formation and its demise in galaxy quenching. We discuss the fundamental problems which quenching aims to solve, various routes to identifying quiescent galaxies in observations, observational constraints on quenching from studies of galaxy populations, and the spatially resolved view of quenching. We end this part of the review with a detailed discussion of the latest results on galaxy quenching at the high redshift frontier from JWST observations.
