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.

本论文的目标是通过研究银河系恒星群体的化学动力学来限制银河系的质量组装历史。该研究将基于从盖亚卫星、SDSS/APOGEE、SDSS/银河系绘图仪和 WEAVE 组合提取的运动学和化学数据。第一步将包括分析 M54 的恒星族含量以及结构和运动学特性，M54 是 Sgr dSph 星系的核星团。这个最初的“破冰”项目旨在让博士生熟悉银河考古学领域所使用的数据和方法，目标是在明年内发表论文。该分析将基于 APOGEE 和 MUSE 数据的组合。该项目结束后，博士候选人将开始对晕恒星群的 WEAVE 和 SDSS 数据进行组合分析，以限制银河系的吸积历史。
