Gravitational Wave Group - R & D for detection of unknown phenomena 'gravitational waves'
SDSS - Making 3-D map of very distant galaxies with specific wide view telescopes as an international collaboration with Princeton University
Theory Group - Theoretical studies for verifying Grand Unified Theory and early Universe
Ashra (All-sky Survey High Resolution Air-shower detector) - The group has developed a new type of detector with wide angle high resolution aiming for monitoring optical and particle radiation from high-energy transient objects. Prototypes were installed on the slopes of the Mauna Loa volcano at about 10,500 feet elevation in 2006 and 2007. Mauna Loa is located in the Big Island in the U.S. state of Hawaii.
High Energy Astrophysics Group - Theoretical studies for pulsars, gamma-ray bursts, AGNs, acceleration mechanisms of particles etc.
