   Lumina simulation reconstructs universe's first 2 billion years

   Astronomers from the Center for Astrophysics | Harvard & Smithsonian developed Lumina, a large-scale supercomputer simulation that recreates the universe's first 2 billion years after the Big Bang. Utilizing the Frontier supercomputer, the model traces the formation of the first stars and galaxies and the reionisation of the early universe. Lumina reconstructs interactions between radiation, dark matter, and ordinary matter, covering 100 times more volume than previous runs. The simulation provides a framework to interpret observations from advanced telescopes and test the existence of surprisingly bright galaxies observed by Webb.

   Why it matters

   The early universe began as a hot, dense plasma of subatomic particles and electrons that expanded and cooled to form neutral hydrogen. This period led into the Cosmic Dark Ages before the first light-producing structures emerged. Understanding this transition helps scientists explain how the current cosmic structure evolved from a primordial soup.

   What is confirmed

   • Lumina is a supercomputer simulation that recreates the first 2 billion years of the universe.
   • The simulation was developed by scientists at the Smithsonian and Harvard.
   • Lumina utilizes the Frontier supercomputer to reconstruct interactions between radiation, dark matter, and ordinary matter.
   • The model traces the formation of the first stars and galaxies and the reionisation of the early universe.
   • Lumina covers 100 times more volume than past simulation runs.
   • The simulation serves as a test for surprisingly bright galaxies observed by the Webb telescope.

   What to watch next

   • Comparison of Lumina simulation data with new observations from the Webb telescope
   • Publication of specific galaxy formation timelines derived from the model
