Astrophysicists working with the James Webb Space Telescope (JWST) have found a surprising amount of metal in a galaxy only 350 million years after the Big Bang.
New research has just answered one of the fundamental questions about our universe: Why did some of the oldest, most massive galaxies go quiescent early in their formation? The answer, we now know, is because they ran out of cold gas.
Astronomers have now found a so-called “cold quasar” in which star formation has managed to continue even in the presence of a ravenous supermassive black hole. The team studied a quasar 5.25 billion light years away.
Astronomers have identified six previously mild-mannered galaxies that suddenly transformed into voracious quasars, erupting in feeding frenzies powered by supermassive black holes.
