Numerical study of the cosmic shear
arXiv:astro-ph/0009459 · doi:10.1007/10854354_71
Abstract
We study cosmic shear statistics using the ray-tracing simulation combined with a set of large $N$-body simulations. In this contribution, we first describe our method. Then we show some selected results especially focusing on effects of the deflection of light rays and the lens-lens coupling which are neglected in making the theoretical predictions of the cosmic shear statistics.
