Welcome to Astronomical Institute, Tohoku University homepage. We are conducting theoretical and observational researches of extra-solar planets, stars, galaxies, clusters of galaxies, and cosmology. Observational researches are conducted using cutting-edge open use facilities such as Subaru telescope. We are also developping unique instruments for large telescopes, to reveal formation and evolution of galaxies.
