Toward understanding rich superclusters

We present a morphological study of the two richest superclusters from the 2dF Galaxy Redshift Survey (SCL126, the Sloan Great Wall, and SCL9, the Sculptor supercluster). We use Mi…

Two-dimensional high-resolution density field of galaxies of the Early Data Release of the Sloan Digital Sky Survey with a smoothing lengths 0.8 h^{-1} Mpc is applied to extract cl…
Correlations in the orientations of galaxy clusters
Andreas Faltenbacher, Martin Kerscher, Stefan Gottloeber +1
The relative orientation of clusters' major elongation axes and clusters' angular momentum is studied using a large N-body simulation in a box of 500 Mpc/h base length for a standa…
Spatial distribution of galactic halos and their merger histories

S. Arbabi-Bidgoli, V. Mueller
An analysis of voids using cosmological N-body simulations of cold dark matter models is presented. It employs a robust statistics of voids, that was recently applied to discrimina…
