Abstract

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.

JWST观测中星系对与并合的最新研究进展

JWST的发射为天文学家带来了大量关于遥远星系的观测数据，这在星系相互作用和星系合并的研究中尤为重要。JWST的红外观测能力为天文学家提供了一个独特的视角，揭示了星系内的气体动力学和恒星形成活动。合并事件在整个宇宙中普遍存在，基于JWST观测数据的研究进一步证实了合并对星系演化的重大影响。在与JWST相关的星系研究方面取得了重大进展，包括统计研究和个别案例研究，以及理论模拟与实际观测的结合。JWST还为观测发射线星系提供了独特的视角，广泛应用于各种红移的研究，特别是高红移星系的研究。JWST在合并星系研究中发挥着至关重要的作用，其红外观测能力为探索星系结构和组成提供了前所未有的优势。它的高分辨率和高灵敏度使其成为研究星系合并的理想工具，为天文学家提供了新的机会，并在更深层次上理解星系演化提出了挑战。

期刊介绍： The vigorous growth of astronomical and astrophysical science in China led to an increase in papers on astrophysics which Acta Astronomica Sinica could no longer absorb. Translations of papers from two new journals the Chinese Journal of Space Science and Acta Astrophysica Sinica are added to the translation of Acta Astronomica Sinica to form the new journal Chinese Astronomy and Astrophysics. Chinese Astronomy and Astrophysics brings English translations of notable articles to astronomers and astrophysicists outside China.
