Hubble sees the brightest quasar in the early universe

NASA / ESA The Hubble Space Telescope discovered the brightest quasar ever seen in the early universe. After 20 years, astronomers searched for the old quasar, using strong gravity. This unique object introduces the birth of galaxies when the universe was over a billion years old

Astronomers, using the NASA / ESA Hubble Space Telescope, discovered the brightest quasar ever seen in the early universe – the journey from the object began when the Universe was just about billion years. A powerful quasar glow is created by a supermasive black hole surrounded by an excise disk. Gases that have fallen into a black hole give rise to incredible amounts of energy that can be observed at all wavelengths

A recently discovered quasar, cataloged as J043947.08 + 1

63415.7 [1] is no exception; its brightness is equivalent to about 600 trillion suns, and the super-black black hole is a few hundred million times more massive than our sun. [2] "It's something we've been looking for for a long time," said head author Xiaohui Fan (University of Arizona, USA). "We do not want to find many quasars that are more prominent than the whole universe we observe."

Despite his brightness, Hubble could only notice it because his appearance was heavily influenced by a strong gravitational lens. The light galaxy is directly between the quasar and the Earth, bending the light from the quasar and making it three times larger and 50 times brighter than without the gravitational lens effect. Even the lens and the objective quasar are extremely compact and unresolved in optical terrestrial telescopes. Only Hubble's eighth vision allowed it to be resolved.

The data show not only that the super-black black hole is very high, but also that the quasar can produce up to 10,000 stars per year [3]. "His qualities and distance become the main candidate for the study of the evolution of the far quasars and the role of superhuman black holes in their center." explains Fabian Walter (Max Planck Institute) Astronomy, Germany, illustrating why such a discovery is so important.

Quasars, similar to J043947.08 + 163415.7, existed in the period of re-regionalization of the young universe, when the radiation of young galaxies and quasars warmed up the unclear water that had cooled down only 400,000 years after the Great Bang; The universe turned away from neutrality and was again ionized in plasma. However, it is not yet known which objects have been submitted for re-regionalization. Energy objects, such as this newly discovered quasar, could help solve this mystery.

For this reason, the team collects as much data as possible about J043947.08 + 163415.7. They are currently analyzing a comprehensive 20-hour spectrum from the very large telescope of the European Southern Observatory, which will allow them to determine the chemical composition and temperature of intergalactic gases in the early universe. The team also uses the Atacama Large Millimeter / Submillimeter Array and hopes to observe the quasar with the upcoming NASA / ESA / CSA James Webb space telescope. With these telescopes they will be able to look at the superplastic black hole and directly measure its gravitational influence on the surrounding gas and star formation

Notes

Further spectroscopic observations were made with a multifunctional telescope, the Twinning Observatory and the Keck Observatory

[2] The brightness of the quasar includes the 50th magnification factor. In addition to gravitational lens magnification, the quasar's brightness is about 11 trillion suns.

[3] Due to the increasing impact of the gravitational lens, the actual rate of star formation may be much lower. For comparison, the Bird Trail creates approximately one new star every year
