| Outline of Final Research Achievements |
We investigated the structure formation in the early universe through various cosmological observations. In particular we focused on the feasibility study of future 21 cm observations as a probe of the structure formation history.
Our main results are as follows; 21cm observations can reveal the statistical nature of the seeds of the cosmological structure over a wide range of scales, 21cm observations can access the epoch of reionization at which first stars and galaxies are produced, 21cm observations can test the theory of gravity.
