Astronomers have discovered the farthest and oldest single source of radio emissions in the known universe. That source is one of the most powerful particle accelerators in the universe: it connects about 13 billion light-year-old particle planes with the speed of Earth’s light.
Quars Some of the oldest, farthest, largest and brightest things in the universe. They form the cores of galaxies where fast-moving supermassive black holes gorge on all things that are unable to escape its gravitational grip. The black hole is raising the issue, emitting so much radiation at the time that it could be trillions of times brighter than massively bright stars, making the brightest objects in the observable universe quarts.

“[G]”These objects are very bright, however, they can be observed from very far away,” Chiara Mazuzchelli, who led the discovery together with Eduardo Badoz, told Live Science. “While galaxy-like galaxies can be discovered and obscured even in the study of this. Distance, when the universe was very small we can use these very bright quarters to study. We are talking about a time when the first The stars and galaxies were formed. “
In particular, this quasar, named P172 + 18, is a relic about 780 million years later. The Big Bang And reveals clues about one of the earliest ages in the universe – The era of reunion. At the beginning of this period, the universe was darkened by a similar cloud of excessive hydrogen gas. Scientists refer to this time as the Dark Ages of the universe, as most of the light is rapidly absorbed by the neutral charge gas. Eventually, gravity broke the primitive gas into the first stars and quasars, which began to heat and ionize the surrounding gases, allowing light to pass through.
The first quasars were observed while using the Magellan telescopes at the Las Campanas Observatory in Chile, by astronomers from the European Southern Observatory in Chile, Zushelli in Germany, and astronomers from the Max Planck Institute for Astronomy in Germany. They observed a telltale radio signature dropped by a powerful jet of particles erupting from above and below a black hole. Superspeed particles emit tremendous amounts Radio waves. Scientists call these quarters “radio-loud” and believe that the jets of their accelerating particles, found in only 10% of the quarks, play a major role in the evolution of the early galaxies.
Further observations of binoculars, including the Cake Observatory in Hawaii and a very large telescope in Chile, show that the P172 + 18 is about 300 million times larger than the Sun and one of the fastest growing quarters ever discovered. The problem is that scientists don’t know how the black hole in the universe became so large at the beginning. Radio jets can be a revelation.
“Theoretical studies say that the presence of radio jets can increase the speed at which a black hole eats, which means that they will allow the black hole to grow faster and explain why. [the black holes] “There’s so much going on so soon,” Mezushelli said. “At the same time, radio jets can also affect the galaxy around Quasar by influencing how stars form.”
However, the feeding frenzy of black holes may not last long. When astronomers compared their recent observations with a survey of the sky more than two decades ago, they found that Kwasar had lost half its brightness, indicating that Kwasar was approaching the end of its life.
Beacons in the dark
Mazusheli described the quarries as distant flashlights that illuminate a specific time and space in the history of the universe. With each new discovery discovered in the timeline between the Big Bang and the universe we find another patch we see today. She is hopeful that the research team will find many more quarters in the near future.
In fact, long after their discovery of P172 + 18, astronomers discovered another son of nearby radio waves. If further observations confirm that this companion radio source is located at the same distance from Quasar, it may be the farthest pair of active galaxies ever found. Researchers hope that NASA’s James Webb will be able to determine the exact distance of a telescopic radio source, such as the Web Space Telescope.
The findings of the researchers will be published in the next issue Astrophysical Journal.
