摘　　要：星系的并合事件在宇宙中普遍存在。JWST的发射升空在光学红外波段打开了新的观测窗口,为深入理解并合在星系演化过程中的作用提供了新的观测机会。JWST的高分辨率和高灵敏度有助于认证和研究星系并合的物理性质和规律,为更高红移和高分辨率的并合星系的观测提供了气体动力学、恒星形成和超大质量黑洞活动的信息,并进一步证实了并合是星系演化中普遍存在的重要阶段。重点介绍了JWST对多个并合星系样本的统计及个例研究,结合了观测和理论模拟的进展,总结了在各红移处,特别是中高红移处的并合星系相关研究中取得的新进展。The launch of JWST has brought astronomers a wealth of observational data on distant galaxies,which is particularly crucial in the study of galaxy interaction and galaxy mergers.JWST’s infrared observation capabilities offer a unique perspective to astronomers,revealing the gas dynamics and star formation activities within galaxies.Merger events are prevalent throughout the universe,and research based on JWST observation data further confirms the significant impact of mergers on galaxy evolution.Significant progress has been made in the study of galaxies associated with JWST,including both statistical studies and individual case studies,as well as the integration of theoretical simulations with actual observations.JWST also provides a unique perspective for observing emission-line galaxies,and it is widely applied in studies across various redshifts,especially in high-redshift galaxy research.JWST plays a vital role in merger galaxy research,with its infrared observation capabilities providing unprecedented advantages in exploring galaxy structure and composition.Its high resolution and sensitivity make it an ideal tool for studying galaxy mergers,offering astronomers new opportunities and posing challenges in understanding galaxy evolution at a deeper level.
