Outline of Final Research Achievements

We aimed for detecting the first moment of explosion of a supernova (shock breakout), which is originated from a massive star, to reveal the final stage of a stellar evolution and the explosion mechanism. We used wide-field optical imaging camera mounted on 1-m Kiso Schmidt telescope (KWFC) and 8.2-m Subaru telescope (HSC). Our high-cadence supernova survey for supernovae was the first trial in the world. We completed observing systems for remote automatic observations for the Kiso telescope and carried out 100-night observations per year for three years. We discovered no shock breakouts which is still consistent with the model prediction. With the Subaru HSC, we developed a data reduction system at the site and successfully discovered 5 young supernovae which are thought to be right after the explosions. Using the same dataset, we also identified a small active black holes of 3 million solar masses.
