Numerical study of the cosmic shear
Takashi Hamana, Stephane Colombi, Yannick Mellier
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.
