Weak gravitational lensing in different cosmologies, using an algorithm for shear in three dimensions
Abstract
We present the results of weak gravitational lensing statistics in four different cosmological N-body simulations. The data have been generated using an algorithm for the three-dimensional shear, which makes use of a variable softening facility for the N-body particle masses, and enables a physical interpretation for the large-scale structure to be made. Working in three dimensions also allows the correct use of the appropriate angular diameter …
