卫星星系数目分布的研究进展

Research Progress on The Number Distribution of Satellite Galaxies

卫星星系存在于暗晕的子结构中,是暗物质晕等级成团的最直接的证据,为了解目前对卫星星系数目分布的研究现状,文章采用文献调查法对卫星星系的数目分布的研究进行了深入的调查,总结了卫星星系数目分布对中央星系的恒星质量的依赖,对星系所处的暗晕质量的依赖,对星系所处的大尺度结构的依赖,也总结了卫星星系的数目对中央星系的颜色和中央星系的形态的依赖。

Satellite galaxies exist in the substructure of dark halos,which is the most direct evidence of the hierarchical clustering of dark matter halos.In order to understand the current research status of the number distribution of satellite galaxies,the paper uses the literature survey method to deeply investigate the number distribution of satellite galaxies,and summarizes the dependence of the number distribution of satellite galaxies on the stellar mass of the central galaxy,and the dependence on the mass of the dark halo in which the galaxy is located and on the large-scale structure in which the galaxy is located.It also summarizes the dependence of the number of satellite galaxies on the color and shape of the central galaxy.
