| Research Abstract |
We studied in the three topics about the dark side of the universe : dark energy, dark matter, and dark age. For dark energy, the design study of galaxy redshift survey using new FMOS instrument of Subaru Telescope has been performed, and the project is close to the realization. For dark matter, we studied about the cosmic gamma-ray background radiation, especially about the contribution from active galactic nuclei and star-forming galaxies. This will become the basis for searching dark matter signal. For the dark age, we continued observational studies of high-redshift universe by gamma-ray bursts, and also we constructed a new model of Lyman alpha emitters, by which we obtained new implications for cosmic reionization.
