Frenetic star-forming activity in the early Universe is linked to the most massive galaxies in today’s cosmos, new research suggests. This “starbursting” activity when the Universe was just a few billion years old appears to have been clamped off by the growth of supermassive black holes.

An international team gathered hints of the mysterious “dark matter” in early galaxies to confirm the link. Being able to see objects at great distances in the cosmos allows astronomers to look into the past, at light that departed when the Universe was young.
