Researchers at the National Observatory of Radio-Astronomy of the United States discovered the most brilliant object of the primitive universe – a quasar located at 13 billion years old. light of the Earth. This is reported by HB with reference to Science Alert.
This quasar was formed when the age of the universe was only seven percent of the present. The quasars are characterized by plasma jets coming out of their center. They are clearly visible in the radio frequency spectrum. This signal came from the quasar identified by the name PSO J352.4034-15.3373 (P352-15 for brevity), which was detected by the Very Long Baseline Array radio telescope. It has, like most quasars, two plasma jets of this type. The light of the quasars can be used to study the intergalactic environment. This is due to the fact that hydrogen changes the spectrum of light in its long journey to Earth.
"We see the object P352-15, appeared when the universe was less than a billion years, at the end of the period, when the first stars and the first Galaxies re-ionize the neutral hydrogen atoms that pierced the intergalactic space. Other observations could allow us to use this quasar as a basis for measuring the amount of neutral hydrogen of the time, "says astrophysicist Chris Carilli of the National Observatory of Radio Astronomy. Super The distance between P352-15 and the Earth still does not determine the mass and size of the galaxy associated, but now, as scientists say, P352-15 is the brightest source of radio waves in the young universe, whose power is tens of times higher than in all other objects known to astronomers.
