Welcome to
Cosmology Group


We tackle mysteries of the Universe using the largest telescopes in the world.

Have you imagened how big the Universe is? When and how supermassive black holes formed? Our group studies observational cosmology using data taken with Subaru 8.2-m telescope and AKARI Infrared space telescope.
