Galaxies reveal hidden maps of dark matter in the early universe
Rutgers UniversityPeer-Reviewed Publication
A Rutgers-led team of scientists has uncovered evidence of how galaxies expand by tracing the invisible scaffolding of the universe created by a mysterious substance known as dark matter.
In a newly published study in Astrophysical Journal Letters, researchers used what they said are the largest-ever samples of special galaxies called Lyman-alpha emitters to study how galaxies clumped together over billions of years. In doing so, they gained an improved understanding of how galaxies relate to the surrounding dark matter and how they evolve over time.
