"Despite the quasar's extreme luminosity, the black hole at its heart was found to have a mass equal to only' around one billion suns, Associate Professor Christian Wolf told ANU Reporter. He added that instead of spinning rapidly as expected, the black hole was belching up gas, driven outwards by the blinding intensity of light. The black hole at the centre of this young galaxy was first detected in 2024 by Wolf and his colleagues at the Australian National University (ANU)."
"We have been wondering for years how it's possible we discovered all these fully grown supermassive black holes in very young galaxies shortly after the Big Bang. They shouldn't have had the time to grow that massive, he told the Press Association (PA). The study, published in Astronomy and Astrophysics, used Gravity+, an instrument that combines light from four of the world's largest telescopes at ESO's Very Large Telescope in Chile."
A team using Gravity+ at the European Southern Observatory observed a quasar in a galaxy more than 12 billion light years away and measured its central black hole mass at about one billion suns, roughly one-tenth previous estimates. The black hole exhibits outflowing gas driven by intense radiation rather than the rapid spin that had been expected. The object was first detected in 2024 and analysis of hot gas spiralling inward provided the new mass estimate. International collaborators from several European countries and the University of Southampton contributed to the study published in Astronomy and Astrophysics.
