【Press Release】Hibernating black holes - Destruction of the central black hole gas reservoir through galaxy collisions


Supermassive black holes exist in the universe that are more than 100,000 times the mass of the Sun, and, although only a small part of them are luminous due to the energy of accreting material, in most galaxies, the central massive black hole is dark and quiet. The mechanism that...

[Press release] The Cosmic Neutrino Background: World's First Six-dimensional Simulations


In this research, we solved the Vlasov-Poisson equations directly by running our new high-precision numerical scheme for solving the Vlasov equation developed by the University of Tsukuba and the University of Tokyo on Japan's most powerful supercomputer, yielding 6-dimensional distributions of the neutrinos permeating our universe. This was the first...
