The nonlinear bispectrum from the CDM N-body simulation
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 4
Abstract
Bispectrum, the three-point correlation function in Fourier space, is the lowest order statistic that probes the shape of the large-scale structures generated by the gravitational clustering. With the two-dimensional and three-dimensional Fast Fourier Transformation, we measured the bispectrum from quasi-nonlinear to strong nonlinear region with N-body simulation of LCDM.
