Outline of Final Research Achievements

Thanks to the observational progress on cosmology, the so-called 'standard cosmological model', which consistently describes the dynamics of cosmic expansion and growth of structure, has been fully established. Since the cosmology in the coming decade is also expected to be driven by the precision observational data set from the systematic large-scale surveys, a development of accurate theoretical template, which will be used to extract the cosmological information from the observational data, is quite crucial. For this purpose, based on the perturbation theory technique of large-scale structure of the Universe, we have developed a high-precision theoretical template for next-generation galaxy surveys. Implementing a fast calculation method for perturbation theory, the cosmological data analysis tool was exploited. Applying it to the existing cosmological data set, robust cosmological test of gravity has been made, and a tight constraint on the cosmic expansion has been obtained.
