The impact of cluster mergers on arc statistics
Elena Torri, Massimo Meneghetti, Matthias Bartelmann +3
We study the impact of merger events on the strong lensing properties of galaxy clusters. Previous lensing simulations were not able to resolve dynamical time scales of cluster len…

Arc statistics with realistic cluster models
Massimo Meneghetti, Matthias Bartelmann, Lauro Moscardini +3
Arc statistics is known to be a powerful cosmological tool. Numerical lensing simulations show that orders of magnitude differences in the number of {\em giant} arcs on the whole s…
