| Outline of Final Research Achievements |
Supernovae are the terminal explosions of massive stars. Recently, supernovae that are more than about 10 times brighter than ordinary supernovae have been discovered and they are called superluminous supernovae. Their progenitors are unknown. This research has revealed that the supernovae that form strongly magnetized rapidly rotating neutron stars during the explosions are likely to be superluminous supernovae. Superluminous supernovae can be observed further than other supernovae. Using Subaru/Hyper Suprime-Cam, this study has led to the discovery of the most distant supernova ever observed. It implies that massive stars are preferentially formed in the early Universe.
