摘要:

利用不同形态类型的化学演化模型,研究了质量-金属丰度(MZ)关系及其随红移的演化。我们的目的是了解不同形态类型的星系在不同红移的MZ关系中的作用。一个主要的结果是,在高红移,大部分的星系落在MZ图显然是原椭圆星系。最后,我们展示了在等级星系形成的框架下研究MZ关系的一些初步结果。

英文摘要:

By means of chemical evolution models of different morphological types, we study the mass-metallicity (MZ) relation and its evolution with redshift. Our aim is to understand the role of galaxies of different morphological types in the MZ relation at various redshift. One major result is that at high redshift, the majority of the galaxies falling on the MZ plot are apparently proto-ellipticals. Finally, we show some preliminary results of a study of the MZ relation in a framework of hierarchical galaxy formation.
