The goal of this project is to assess the contribution of dissolved globular clusters to the stellar mass budget of the various Galactic components (halo, disk, bulge/bar) and compare the results with the predictions of state of the art numerical simulations, in order to constrain the history of formation and mass assembly of the Milky Way Galaxy. In order to identify tracers of globular cluster dissolution in the field of the Galaxy, we will perform chemical tagging based on the the huge sample from the the SDSS/APOGEE survey. The observational data will be compared with state of the art numerical simulations from the E-MOSAICS project.

该项目的目标是评估溶解的球状星团对银河系各种组成部分（晕、盘、凸起/棒）的恒星质量预算的贡献，并将结果与最先进的数值模拟预测进行比较，以限制银河系形成和质量组装的历史。为了在银河系领域中识别球状星团溶解的示踪物，我们将根据SDSS/APOGEE巡天的巨大样本进行化学标记。观测数据将与E-MOSAICS项目的最新数值模拟进行比较。
