Gravitational lensing studies of high resolution cluster simulations L.J.King et al. ... These simulations performed by Springel and White have a soft- ening length of 0.7kpc/h and a particle mass of 4.6810 7 solar masses. A cluster acting as a gravitational lens distorts the number density and shapes of background galaxies, and can also create multiple images. Synthetic data sets which mimic the action of such a cluster as a lens can be created. ...
