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…
Resolving the line-of-sight structure of galaxy clusters by combining X-ray and lensing data
Matthias Bartelmann, Tsafrir S. Kolatt
The projected gravitational potential of galaxy clusters is reflected in both their X-ray emission and their imprint on the images of background sources due to their gravitational…
