Theoretical predictions have been confirmed with the discovery of an outflow of molecular gas from a quasar when the Universe was less than a billion years old.

Machine learning and state-of-the-art supernova nucleosynthesis has helped researchers find that the majority of observed second-generation stars in the universe were enriched by multiple supernovae.

When two neutron stars merge, the resultant explosion forms heavy elements—many of which make up our Universe. A new study has, for the first time, identified the specific rare-earth elements produced in a neutron star merger.

COW and GEP are new types of exploding stars. Researchers have succeeded in explaining the features of a new type of supernova which appears ten to a hundred times brighter at its peak, and with a much faster rise toward the peak compared to an ordinary supernova.

A research team including Kavli IPMU Principal Investigator Naoki Yoshida has, in a world first, succeeded in performing a 6-dimensional simulation of neutrinos moving through the universe.

Neon inside a certain star core can eat so many electrons, it causes the star to collapse into a neutron star and produce a supernova.

The origin of how the Universe created its voids and filaments can now be studied within seconds after researchers developed an artificial intelligence tool called Dark Emulator.
