The Topology of Large Scale Structure in the 1.2 Jy IRAS Redshift Survey
Zacharias A. M. Protogeros, David H. Weinberg
We measure the topology (genus) of isodensity contour surfaces in volume limited subsets of the 1.2 Jy IRAS redshift survey, for smoothing scales $λ=4\hmpc$, $7\hmpc$, and $12\hmpc…
Testing Tree-Level Perturbation Theory for Large-Scale Structure with the Local Lagrangian Approximation
Zacharias A. M. Protogeros, Adrian L. Melott, Robert J. Scherrer
We test tree-level perturbation theory for Gaussian initial conditions with power spectra by comparing the probability distribution function (PDF) for the density…
Skewness of the Large-Scale Velocity Divergence from Non-Gaussian Initial Conditions
Zacharias A. M. Protogeros, Robert J. Scherrer
We compute the skewness and the corresponding hierarchical amplitude of the divergence of the velocity field for arbitrary non-Gaussian initial conditions. We find that…
Local Lagrangian Approximations for the Evolution of the Density Distribution Function in Large-Scale Structure
Zacharias A. M. Protogeros, Robert J. Scherrer
We examine local Lagrangian approximations for the gravitational evolution of the density distribution function. In these approximations, the final density at a Lagrangian point q…
