Filaments and Pancakes in the IRAS 1.2 Jy Redshift Catalogue
B. S. Sathyaprakash, Varun Sahni, Sergei F. Shandarin +1
We explore shapes of clusters and superclusters in the IRAS 1.2 Jy redshift survey with three reconstructions spanning the range β= 0.1, 0.5, 1.0, where β= Ω^{0.6}/b, b is the bias…
Skewed exponential pairwise velocities from Gaussian initial conditions
Roman Juszkiewicz, Karl B. Fisher, Istvan Szapudi
Using an Eulerian perturbative calculation, we show that the distribution of relative pairwise velocities which arises from gravitational instability of Gaussian density fluctuatio…
Redshift-Space Distortions and the Real-Space Clustering of Different Galaxy Types
Luigi Guzzo, Michael A. Strauss, Karl B. Fisher +2
We study the distortions induced by peculiar velocities on the redshift-space correlation function of galaxies of different morphological types in the Pisces-Perseus redshift surve…
Wiener Reconstruction of the IRAS 1.2Jy Galaxy Redshift Survey: Cosmographical Implications
Matthew Webster, Ofer Lahav, Karl Fisher
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 res…
Percolation Analysis of a Wiener Reconstruction of the IRAS 1.2 Jy Redshift Catalog
Capp Yess, Sergei F. Shandarin, Karl B. Fisher
We present percolation analyses of Wiener Reconstructions of the IRAS 1.2 Jy Redshift Survey. There are ten reconstructions of galaxy density fields in real space spanning the rang…
The Signature of a Correlation between Cosmic Ray Sources and Large Scale Structure
Eli Waxman, Karl B. Fisher, Tsvi Piran
We analyze the anisotropy signature expected if the high energy (above eV) cosmic ray (CR) sources are extra-Galactic and trace the distribution of luminous matter on larg…
