论文摘要
我们总结了对银河系光环，磁盘和凸起中恒星种群的分析的分析结果的最新结果，从而构成了矮星系和球状簇对晕光的恒星含量的贡献的限制。根据宇宙学数值模拟对现有数据的解释表明，银河系在z> 〜1.5处受到异常强烈的积聚史的影响。
We summarise recent results from analysis of APOGEE/Gaia data for stellar populations in the Galactic halo, disk, and bulge, leading to constraints on the contribution of dwarf galaxies and globular clusters to the stellar content of the Milky Way halo. Interpretation of the extant data in light of cosmological numerical simulations suggests that the Milky Way has been subject to an unusually intense accretion history at z >~ 1.5.
