PERCOLATION ANALYSIS OF A WIENER RECONSTRUCTION OF THE IRAS 1.2Jy REDSHIFT CATALOG

چکیده

We present percolation analyses of Wiener Reconstructions of the IRAS 1.2Jy Redshift Survey. There are ten reconstructions of galaxy density in real space spanning the range β = 0.1 to 1.0, where β = Ω/b, Ω is 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 the density field, where Gaussian randomized versions of the reconstructions are used as standards for analysis. For the reconstruction volume of radius, R≈100hMpc, percolation analysis reveals a slight ‘meatball’ topology for the real space, galaxy distribution of the IRAS survey.

WIENER RECONSTRUCTION OF THE IRAS 1.2Jy GALAXY REDSHIFT SURVEY: COSMOGRAPHICAL IMPLICATIONS

We utilise the method of Wiener reconstruction with spherical harmonics and Bessel functions to recover the density and velocity fields from the IRAS 1.2Jy redshift survey. The reconstruction relies on prior knowledge of the IRAS power-spectrum and the combination of density and bias parameters β ≡ Ω/b. The results are robust to changes in these prior parameters and the number of expansion coef...

We utilise the method of Wiener reconstruction with spherical harmonics and Bessel functions to recover the density and velocity elds from the IRAS 1.2Jy redshift survey. The reconstruction relies on prior knowledge of the IRAS power-spectrum and the combination of density and bias parameters 0:6 =b. The results are robust to changes in these prior parameters and the number of expansion coeecie...

We explore shapes of clusters and superclusters in the IRAS 1.2Jy redshift survey with three reconstructions spanning the range β = 0.1, 0.5, 1.0, where β = Ω/b, b is the bias factor and Ω the present value of the dimensionless matter density. Comparing our results to Gaussian randomized reconstructions of the IRAS catalogue, we find structures having both planar and filamentary properties. For...

Reconstruction Analysis of the Iras Point Source Catalog Redshift Survey

We present the results of reconstruction analysis of the galaxy distribution in a spherical region of radius 50 h~1 Mpc centered on the Local Group, as mapped by the IRAS Point Source Catalog Redshift Survey (PSCz). We reconstruct this galaxy distribution using 15 di†erent models for structure formation in the universe, each model consisting of a set of assumptions regarding the value of the co...

Reconstructing the ZOA from Galaxy Peculiar Velocities

Galaxy peculiar velocity data provide important dynamical clues to the structures obscured by the Zone of Avoidance (hereafter, ZOA) with resolution > ∼ 500 km s . This indirect probe complements the very challenging approach of directly mapping of the distribution of galaxies behind the Milky Way. In this work, the Wiener filter method is applied to reconstruct the 3D density and velocity dist...
