The Three-point Correlation Function of Galaxies: Comparing Halo Occupation Models with Observations
Yu Wang, Xiaohu Yang, H. J. Mo +2
We present models for the three-point correlation function (3PCF) of both dark matter and galaxies. We show that models based on the halo model can reasonably match the dark matter…

Spatial Locality of Galaxy Correlation Function in Phase Space: Samples from the 2MASS Extended Source Catalog
Yicheng Guo, Yao-Quan Chu, Li-Zhi Fang
We analyze the statistical properties and dynamical implications of galaxy distributions in phase space for samples selected from the 2MASS Extended Source Catalog. The galaxy dist…

Populating Dark Matter Haloes with Galaxies: Comparing the 2dFGRS with Mock Galaxy Redshift Surveys
Xiaohu Yang, H. J. Mo, Y. P. Jing +2
In two recent papers, we developed a powerful technique to link the distribution of galaxies to that of dark matter haloes by considering halo occupation numbers as function of gal…
