Percolation Analysis of a Wiener Reconstruction of the IRAS 1.2 Jy Redshift Catalog

摘要

We present percolation analyses of Wiener reconstructions of the IRAS 1.2 Jy redshift survey. There are 10 reconstructions of galaxy density fields in real space spanning the range β= 0.11.0, where β= ω~0.6/b, ωis the present dimensionless density, and b is the bias factor. Our method uses the growth of the largest cluster statistic to characterize the topology of a density field, where Gaussian randomized versions of the reconstructions are used as standards for analysis. For the reconstruction volume of radius R ≈100 h-1 Mpc, percolation analysis reveals a slight "meatball" topology for the real space, galaxy distribution of the IRAS survey.
