Research History

Searches for the most distant galaxies. Surveys of the galaxy evolution and cosmic reionization in the early universe. By observing distant galaxies in the early universe, I have tried to reveal how the galaxies have been formed and evolved in the history of the Universe.

Research Plan at GCOE

When and how cosmic reionization started and ended, what was the primary source of reionization, when and how the galaxies formed and evolved to the present day remain fundamental subjects of observational cosmology. Studying galaxies and other objects within the first 1 billion years after the Big Bang is important to constraining the epoch of reionization and galaxy evolution in the early Universe. I analyze photometric and spectroscopic data of galaxies and investigate in details reionization state and galaxy evolution within the first 1 billion years of the history of the Universe from the statistical and physical properties of galaxies.


I do my best to obtain the research results that will have a big impact and contribute to the development of astronomy and astrophysics.
