GoKawiilHarvard-Smithsonian team unveils Lumina Project, largest early-universe simulation to date
Researchers at the Center for Astrophysics, a Harvard-Smithsonian collaboration, published the Lumina Project in Monthly Notices of the Royal Astronomical Society, modeling the first 2 billion years of cosmic history across a cube about 1.5 billion light-years wide. The simulation was run on Oak Ridge National Laboratory's Frontier supercomputer using roughly 15,000 of its 37,000 GPUs, surpassing the 2022 Thesan simulation in both scale and timespan covered.
