A team including the Kavli IPMU has observed a pair of galaxies merging 12.8 billion years ago, forming one of the brightest objects in the early Universe. These results will help us understand the early evolution of galaxies and black holes.

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.
