Research Abstract

It has been known that the expansion of the present universe is accelerating which is beyond the scope of present theory of gravity. The dark energy which causes repulsive force and some modification of Einstein theory of gravity are proposed as the reason for the acceleration. However theoretical understanding of these proposals is still very poor. Thus it is argent to have observational study for the origin of the accelerated expansion. The purpose of this study is to develop a new theoretical method of gravitational lensing in order to study the origin of the accelerated expansion based on large scale galaxy survey using newly developed prime forcus camera of Subaru telescope.
