Astronomers have discovered a monster black hole at the cosmic dawn of our Universe powering an ultraluminous, high-energy quasar.
The huge black hole has a mass 12 billion times that of the Sun and its associated quasar pumps out energy a million billion times that of the Sun.
Quasars are formed as the central supermassive black hole sucks in surrounding materials and gases, which heats up and emits a tremendous amount of light, so much that it actually push away the material getting sucked in behind it. It is quasars that limit the growth of black holes, which is one of the reasons why this ultraluminous quasar around this gigantic black hole is so puzzling.
The other reason is how ancient they are. The quasar is in the high redshift of light, which is a measure of how much the wavelength of the light has been stretched by the expansion of the Universe before it reaches us here on Earth. Using this measure, scientists are able to date quasars and they’ve put this one in the early cosmic dawn, just 900 million years after the Big Bang.
