MW halo. III. Statistical chemical abundances

We find that the relative contribution of satellite galaxies accreted at high redshift to the stellar population of the Milky Way's smooth halo increases with distance, becoming...我们发现，在高红移（high redshift）阶段被吸积的卫星星系（satellite galaxies）对银河系平滑银晕（Milky Way's smooth halo）的恒星族群（stellar population）的相对贡献随距离增大而提升，最终变为……
