The first data release of HyperMillennium cosmological simulation
Publish Time:2026-04-23 
The HyperMillennium is a trillion-level simulation; its completion represents a significant leap in computational cosmology. The simulation follows 4.2 trillion dark matter particles within a volume of 50.4 Gpc cubed. Designed to support next-generation galaxy surveys, the simulation achieves a mass resolution of around 500 million solar masses, enabling the detailed study of rare, massive structures, large-scale structures and structure formation.  The entire simulation contains various data outputs, including particle snapshots, FoF groups/substructure catalogues, merging tree and mock galaxy catalogues. 

The current data release originated from the lead paper of the HyperMillennium project, which includes nine Abell 2744 analogues with various information about their member galaxies.
