[Legacy Report] Technical Meeting


Recently dramatical improvement of accuracy and expansion of the size of
the astronomical observations have made cosmology a precise science. In
particular galaxy survey which observes more than billion galaxies in
detail has revealed the structure of the Universe and the energy content
of the Universe very precisely. In this talk, I will introduce the ideas
how we can obtain the insights of expansion history of the Universe by
observing large-scale structure, density fluctuations of galaxies or
dark matter over the cosmological scale as well as the state-of-the-art
of the constraint on the cosmological models. The talk begins with the
introductory of the basic physics explaining the expansion of space-time
and goes into my recent works on testing the cosmological models by
means of void structure.
