原初连续功率谱宇宙模型下暗物质晕的质量函数
The mass function of dark matter haloes in a cosmological model with a running primordial power spectrum

通过研究半解析和流体动力学两种星系形成模型,我们发现,暗物质晕中的星系分布对晕的形成时间也有强烈的依赖性。
We find that , in halos of fixed mass , the number of satellite galaxies has a strong dependence on the halo age , with fewer satellites in older halos .

利用高精度宇宙学数值模拟数据,我们分别对不同暗物质模型下暗晕的角动量分布和LCDM模型下暗晕中暗物质和气体的角动量分布做了具体的分析研究。
We study the angular momentum profile both for dark matter and for gas within virial-ized halos , using statistical samples drawn from different sets of high-resolution cosmological simulations .
