New Simulation 'Lumina' Models Early Universe on Record Scale

• Lumina is one of the largest and most detailed simulations of the early universe created to date.
• It was developed by researchers at the Center for Astrophysics | Harvard & Smithsonian.
• Lumina runs on the Frontier supercomputer, surpassing previous simulations like Illustris TNG in scale and detail.
• The simulation aims to assist astronomers in understanding observations from the James Webb Space Telescope and Nancy Roman Space Telescope.
• Lumina helps explain the universe's reionization period, a key phase in cosmic history.
