An article published in “The Astrophysical Journal” reports a study on the galaxy CQ 4479, where a quasar was observed, an active galactic nucleus with a supermassive black hole that is devouring large amounts of matter, and at the same time an intense star formation. A team of researchers used the SOFIA flying telescope to observe CQ 4479, and found this situation called a cold quasar because the active galactic nucleus is very hot but the galaxy also contains cold gas that gives birth to new stars. This is a rare case that could show an astronomically short period in the evolution of a galaxy before the quasar starts inhibiting star formation.
