Radio astronomy Ph.D. candidate Ruby Byrne agrees that “Epoch of Reionization (EoR)” is a mouthful of jargon. But it simply refers to an exciting time in the universe’s history when stars and galaxies first turned on and lit up the heavens.
The EoR also goes by the name of “cosmic dawn,” said Byrne. And understanding this cosmic dawn — which happened a few hundred million years after the Big Bang — would give us deeper insight into dark matter, star and galaxy formation, and dark energy in the early universe, as well as dating the EoR more accurately.
