COLIBRE Project Simulates Cosmic Evolution, Faces JWST Mysteries

4/20/2026

Summary

Story summary

The COLIBRE virtual universes project, led by Leiden University, models cosmic evolution from the Big Bang to the present, simulating galaxies with cold gas and dust.
The simulations accurately represent galaxy formation and growth and align with James Webb Space Telescope observations.
However, they cannot explain 'little red dots' observed by JWST, which may be early black hole seeds.
The project involves multiple universities across Europe and the United States.
