Most Distant Quasar Discovered Sheds Light On How Black Holes Grow
13/01/2021 12:00 // Slashdot
fahrbot-bot shares a report from Phys.Org: A team of astronomers led by the University of Arizona has observed a luminous quasar 13.03 billion light-years from Earth -- the most distant quasar discovered to date. Dating back to 670 million years after the Big Bang, when the universe was only 5% its current age, the quasar hosts a supermassive black hole equivalent to the combined mass of 1.6 billion suns. In addition to being the most distant -- and by extension, earliest -- quasar known, the object is the first of its kind to show evidence of an outflowing wind of super-heated gas escaping from the surroundings of the black hole at a fifth of the speed of light. In addition to revealing a strong quasar-driven wind, the new observations also show intense star formation activity in the host galaxy where the quasar, formally designated J0313-1806, is located. The researchers will present their findings, which have been accepted for publication in Astrophysical Journal Letters, during a press conference and a scientific talk at the 237th Meeting of the American Astronomical Society, which will be held virtually Jan. 11-15.
