Summary
A Harvard-Smithsonian team published Lumina on Monday, calling it the largest cosmological radiation-hydrodynamics simulation yet of the universe’s first 2 billion years.
15,000-plus GPUs powered the model, which tracks how ordinary matter, dark matter and radiation interacted as the earliest galaxies formed and transformed surrounding gas.
JWST and the upcoming Nancy Roman Space Telescope are a key target: researchers say comparing their observations with Lumina’s predictions can test whether current post-big-bang theories still hold.
The study, published in Monthly Notices of the Royal Astronomical Society, gives astronomers a new benchmark for interpreting the early universe now coming into view through next-generation telescopes.
Will Lumina's unprecedented virtual universe match the surprising early-galaxy chemical discoveries recently captured by the James Webb Space Telescope?
Can an exascale supercomputer recreating half a trillion cosmic elements finally reveal how the first supermassive black holes ended the dark ages?
