| Outline of Final Research Achievements |
Supernova explosions are responsible for the existence of life itself, for they are the source of all elements heavier than helium. The next galactic supernova will provide unprecedented opportunities for scientific study. To look inside the exploding star itself and get the most complete picture, it will be necessary to have both the best possible theoretical models of supernova explosions, as well as the best possible experimental observations of supernova neutrinos.
On the experimental side, we upgraded the famous Super-Kamiokande neutrino detector. This was accomplished by dissolving tons of a special element, gadolinium, in its water in order to make the detector more sensitive to supernova neutrinos. On the theory side, we performed new simulations of supernova explosions on the K-computer. We applied this simulation data to the analysis of neutrino bursts, gravitational waves, and collective oscillations. We made predictions of the neutrino burst events at Super-Kamiokande.
