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. The detector system was 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 of Hawaii in the state of Hawaii. The detector system is currently operational.
High Energy Astrophysics Group - Theoretical studies for pulsars, gamma-ray bursts, AGNs, acceleration mechanisms of particles etc.
