Neutrino and Astrophysics Research

This division aims to study particle physics with prime interests in physics of neutrinos and proton decay, and astroparticle physics with the use of underground experimental facilities like Super-Kamiokande.

Neutrino and Astrophysics Research

Super-Kamiokande

Super-Kamiokande aims to reveal the Universe’s history and to explore the nature of elementary particles through the observation of neutrinos and a discovery of proton decay.

Neutrino and Astrophysics Research

T2K

A neutrino experiment designed to investigate how neutrinos change from one flavour to another as they travel (neutrino oscillations) with an intense beam of muon neutrinos generated at the J-PARC and the Super-Kamiokande neutrino detector.

Neutrino and Astrophysics Research

XMASS

XMASS experiment aims to detect the cold dark matter in the universe directly using a liquid Xenon detector. The detector holds about 1ton of liquid Xenon and has been operated in the Kamioka mine.

Neutrino and Astrophysics Research

Hyper-Kamiokande

The Hyper-Kamiokande detector is planned to consist of an order of magnitude larger tank than predecessor experiment Super-Kamiokande's and ultra high sensitivity photosensors. It is the aim of Hyper-Kamiokande to elucidate the Grand Unified Theory and the history of the evolution of the Universe through an investigation of proton decay and CP violation, together with the observation of neutrinos from supernova explosions.

High Energy Cosmic Ray Research

There are three major experimental research activities in this division, the study of high energy gamma rays and the development of the next generation gamma-ray telescopes, extremely high energy cosmic rays, and very high energy cosmic rays and gamma rays.

High Energy Cosmic Ray Research

Telescope Array(TA)

Aiming at highest energy cosmic ray physics by detecting weak light from atmosphere.

High Energy Cosmic Ray Research

Tibet ASγ Experiment

Search for point sources of VHE cosmic gamma at Tibet heights.

High Energy Cosmic Ray Research

High Energy Astrophysics

High Energy Astrophysics Group studies various high-energy astrophysical objects, which are sources of cosmic rays, via mainly theoretical method.

High Energy Cosmic Ray Research

ALPACA Experiment

Observation of UHE cosmic gamma rays and cosmic rays at Mt. Chacaltaya, Bolivia.

Astrophysics and Gravity Research

This division consists of Gravitational Wave Group, The Observational Cosmology Group and Theory Group.

Astrophysics and Gravity Research

Gravitational Wave

We aim to promote gravitational wave astronomy by participating the world gravitational wave observation network with the large-scale cryogenic gravitational wave telescope, KAGRA.

Astrophysics and Gravity Research

Observational Cosmology

Armed with the state-of-the art telescopes such as Subaru and Hubble, we aim to push the today's observational frontier towards the very high redshift universe that no one has ever seen by observations. Our goal is understanding physical processes of galaxy formation at the early stage and the relevant event of cosmic reionization.

Astrophysics and Gravity Research

Theory

Theoretical studies for verifying Grand Unified Theory and early Universe.
