基于杨小虎的博士论文<宇宙大尺度结构的统计研究>中第4部分内容整理缩写而成.讨论如何利用星系-星系的弱引力透镜观测来获得星系光度-暗物质晕质量之间的关系;并介绍建立的条件光度函数模型,在这个模型中预言了给定质量的暗物质晕中所能形成的不同光度的星系的概率.这些结果给出了讨论星系形成理论中各种物理过程的判据.基于这个模型还预言了一些宇宙中光的分布行为:如宇宙中超过一半的光是来自质量小于1012太阳质量的暗物质晕中.

In this paper we summarize part of our work presented in the thesis of Yang, et al. entitled"The Statistical Research of Large Scale Structure in The Universe". There are four chapters in the thesis: chapter 1, the background of the large scale structure and galaxy formation; chapter 2,constructing a LAMOST mock catalogue; chapter 3, the applications of the discrete wavelet transformation in the large scale structure studies; and chapter 4, linking the galaxies with dark matter halos. Here we focus on the work presented in chapter 4, where we used the weak lensing measurements to constrain the galaxy luminosity-dark matter halo relations and established a conditional luminosity function model Φ(L|M)dL, which gives the number of galaxies with luminosities in the range (L±dL)/2 that reside in a halo of mass M. The conditional luminosity function derived from the present data plays an important role in the establishing of the galaxy formation models and can help us to predict several statistics about the distribution of galaxy light in the local Universe. We show that roughly 50 percent of all light is produced in haloes less massive than 2×1012h-1M⊙.
