标题： The Formation and Evolution of Disk Galaxies

摘要： 我们回顾了我们在分层结构形成框架下模拟盘星系形成的一些最新进展。 我们的模型不仅与本地观测一致，还能很好地描述红移z~1范围内的盘演化。 我们利用该模型来解释关于红移z~3处Lyman-break星系（LBGs）的最新观测结果。 假设这些星系与最 massive 的暗物质晕相关，并采用它们恒星形成率的经验定律，我们发现LBG群体的许多特性，包括它们的相关性、大小和运动学特征都可以在该模型中得到解释。 显示英文摘要

摘要： We review some of our recent progress in modelling the formation of disk galaxies in the framework of hierarchical structure formation. Our model is not only consistent with the local observations, but also provides a good description of disk evolution out to redshift z~1. We use this model to interpret recent observational results on Lyman-break galaxies (LBGs) at z~3. Assuming that these galaxies are associated with the most massive halos and adopting an empirical law for their star formation rates, we find that many properties of the LBG population, including their correlations, sizes and kinematics can be accommodated in the model.
