As an astronomer, I chase after transient and explosive phenomena in the Universe, including supernovae, gamma-ray bursts, and investigate the origins of these enigmatic events in the context of stellar evolution. My approach is a combination of theory and observation. The theoretical study is primary on multi-dimensional hydrodynamics, nuclear reactions, and radiation transport, mostly done by computer simulations. It is also a great pleasure to test the theory by observational data. I propose observing projects for ground and space telescopes at various wavelengths, from infrared through gamma-rays, and conduct observations, e.g., by the Suabru telescope on the sumit of Maunakea, Hawaii, where I frequently visit for the observation.
Aims of the reseach include: To fully understand the still-unknown mechanisms of these most energetic explosive events in the present Universe, to provide solid basis of using these luminous objects in the Cosmological study, and to come up with new ideas to prove the evolution of the Universe.
