本项目拟利用已有的SDSS的测光、光谱数据（含LAMOST）和正在进行中的MaNGA项目的积分视场光谱数据对近域宇宙（z<0.1)中的星系对开展详细研究。研究分为两个方向：一是宏观上利用统计研究方法探讨星系对的各项统计特征，如二元光度函数、恒星形成、AGN比例等，并重点考察这些统计特征与星系对所处的环境之间的关系；二是利用SDSS IV中MaNGA项目分析星系相互作用中的微观物理过程，如恒星形成区域、动力学扰动特征等、并探讨这些物理特征与并合轨道角动量方向、大尺度环境等参数之间的关系。通过本项目，我们希望能够进一步深入了解星系并合过程中的各种物理过程，以及星系演化过程中局域环境和大尺度环境分别所起的作用。

This project aims to use the photometry, spectroscopy data and the ongoing integrated field spectroscopy data from SDSS(also including LAMOST) to make a detailed study on the galaxy pairs in local universe(z<0.1). Our studies include two branches. One is using the large sample of galaxy pair to study their statistical properties, e.g. the bivariate luminosity function, AGN fraction etc., ad their possible connections with large-scale environment. The other direction of our studies focuses on the MaNGA observations of our galaxy pair sample. From MaNGA data, we will derive the detailed physical properties of each pair, e.g. the star formation area, the tidal tails etc. With a statistical sample, we will further investigate the connections of these physical processes with the merging orbits and large scale environment. With this project, we hope to make a progress on understanding the galaxy merging process in more detail and have a better understanding on the impact of the local and large scale environment on the galaxy evolution.
