WASHINGTON — When galaxies initially formed, they weren’t the first in the cosmic neighborhood. The supermassive black holes, which reside at the center of galaxies, probably moved in first, a new astronomy study suggests.
Measurements from radio telescopes looking at the early universe hint at that answer to this cosmic chicken-and-egg question of whether the galaxy or its supermassive black hole existed first.
The new research was presented Wednesday at the American Astronomical Society in Long Beach, Calif.
