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…
