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.

本论文的目的是通过研究其恒星种群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Gaia卫星，SDSS/Apogee，SDSS/Mirky Way Mapper和Weave的组合中提取的运动学和化学数据。第一步将包括对恒星种群含量以及M54的结构和运动特性的分析，M54是SGR DSPH星系的核簇。这个最初的“破冰船”项目旨在使PhD候选人熟悉银河考古学领域中使用的数据和方法，目的是在明年的时间内发表出版物。该分析将基于Apogee和Muse数据的组合。在该项目结束后，博士候选人将开始分析Halo Stellar群体的编织和SDSS数据的组合，以限制银河系的积聚历史。
