Quantitative Analysis of the Void Size Distribution in the LCRS and in CDM Models
V. Mueller, S. Arbabi-Bidgoli
We have analyzed the size distribution of voids in 2D slices of the Las Campanas Redshift Survey (LCRS). The characteristic sizes show a scaling with the mean galaxy…
Quantifying Substructure in Galaxy Clusters
Alexander Knebe, Volker Mueller
Substructure in galaxy clusters can be quantified with the robust Delta statistics (Dressler and Shectman 1988) which uses velocity kinematics and sky projected positions. We test…
Redshift dependence of clustering in numerical simulations
Volker Mueller
High resolution -body simulations for variants of the CDM model are used to derive the redshift dependence of galaxy formation and of galaxy correlation functions. The reconstru…
SIMULATING LARGE-SCALE STRUCTURE FORMATION FOR BSI POWER SPECTRA
V. Mueller
A double inflationary model provides perturbation spectra with enhanced power at large scales (Broken Scale Invariant perturbations -- BSI), leading to a promising scenario for the…
