| Research Abstract |
We utilize galaxy distributions to reveal the time evolution of dark energy, which is the biggest mystery of modern cosmology. For that, we carried out huge numerical simulations and obtained one of the biggest galaxy samples in the world. Using our galaxy sample, we solve trajectories of the light ray in the simulation box, which are suffered from the gravitational lensing effect caused by dark matter distributions. We could estimate future observational errors of parameters to determine dark energy time evolution by these ray-tracing simulations, and propose an optimal observational strategy. These data are open for public.
