The non-linear evolution of bispectrum from the scale-free N-body simulation
Y. H. Hou, Y. P. Jing, D. H. Zhao +1
We have accurately measured the bispectrum for four scale-free models of structure formation with the spectral index , 0, -1, and -2. The measurement is based on a new method…

Mass and Redshift Dependence of Dark Halo Structure
D. H. Zhao, Y. P. Jing, H. J. Mo +1
Using a combination of N-body simulations with different resolutions, we study in detail how the concentrations of cold dark matter (CDM) halos depend on halo mass at different red…
