Story summary

A Rutgers-led team analyzed over 14,000 ancient galaxies to map dark matter distribution in the early universe.
They found that only 3% to 7% of dense dark matter regions contain Lyman-alpha emitting galaxies, which shine for 40 to 180 million years.
The study utilized data from the ODIN survey, focusing on three epochs post-Big Bang.
Dark matter, making up about 85% of the universe, is crucial for galaxy formation.
These findings enhance models of cosmic structure and galaxy evolution, with future studies planned to further investigate dark matter's role.
