On Arcs and Omega
Matthias Bartelmann, Andreas Huss, Joerg M. Colberg +2
The gravitational lens effect of galaxy clusters can produce large arcs from source galaxies in their background. Typical source redshifts of ~ 1 require clusters at z ~ 0.3 for ar…

Arc statistics with realistic cluster potentials. IV. Clusters in different cosmologies
Matthias Bartelmann, Andreas Huss, Joerg M. Colberg +2
We use numerical simulations of galaxy clusters in different cosmologies to study their ability to form large arcs. The cosmological models are: Standard CDM (SCDM; Omega_0=1, Omeg…

The Formation and Evolution of Clusters of Galaxies in Different Cosmogonies
A. Huss, B. Jain, M. Steinmetz
The formation of galaxy clusters in hierarchically clustering universes is investigated by means of high resolution N-body simulations. The simulations are performed using a newly…
