Energetic Phenomena in the Universe

Novae, supernovae, and gamma ray bursts are energetic explosions that take place in various places in the universe. Recently, astronomers have tracked down the source of gravitational waves and discovered the first-observed kilonova explosion caused by neutron star mergers. These explosive phenomena are considered to play a major role in producing heavy elements in the universe. Their study leads us to deeper understanding of the evolution of matter in the universe. Using the unique capability of the Subaru Telescope, astronomers have been conducting cutting-edge study in this field. For example, Subaru’s wide-field camera enabled to discover explosions in the universe.
Detailed observations of individual explosions revealed the site
where elements are produced.
