The History of the Milky Way from the Chemodynamics of its Stellar Populations

本论文的目的是通过研究银河系恒星群的化学动力学来约束银河系的质量聚集史。这项研究将基于从盖亚卫星、SDSS/APOGEE、SDSS/Milky Way Mapper和WEAVE组合中提取的运动学和化学数据。第一步将包括对Sgr dSph星系核心星团M54的恒星数量、结构和运动特性的分析。这个最初的“破冰”项目旨在让博士候选人熟悉银河考古学领域使用的数据和方法，目标是在明年发表一篇论文。这项分析将基于APOGEE和MUSE数据的结合。在该项目结束后，博士候选人将开始分析WEAVE和SDSS关于光环恒星种群的数据，以约束银河系的吸积历史。

The goal of this thesis is to constrain the mass assembly history of the Milky Way through study of the chemodynamics of its stellar populations. The study will be based on kinematics and chemical data extracted from a combination of the Gaia satellite, SDSS/APOGEE, SDSS/Milky Way Mapper, and WEAVE. The first step will consist of an analysis of the stellar population content as well as structural and kinematic properties of M54, which is the nuclear cluster of the Sgr dSph galaxy. This initial "ice-breaker" project is aimed at familiarizing the PhD candidate with the data and methods employed in the field of Galactic Archaeology, with the goal to deliver a publication within the next year. This analysis will be based on a combination of APOGEE and MUSE data. Upon conclusion of this project the PhD candidate will start the analysis of a combination of WEAVE and SDSS data on halo stellar populations, to constrain the accretion history of the Milky Way.
