Scientists have discovered a cosmic body that shines like 600 trillion suns



Scientists have discovered the energetic core of the distant galaxy, recorded in dust from the earliest record of the brightest object of the early universe and shining like 600 trillion suns. Researchers have discovered the object – a black hole quasar – by accidentally sorting a pale-close galaxy whose gravity has enhanced the light of the far quasar.

The quasar is 12.8 billion light-years and shines in the heart of the nascent galaxy at the beginning of the history of the universe, the so-called rejection age when the first stars and galaxies began to burn in neutral cosmic hydrogen. Researchers announced the opening of the Winter Astronomical Society session in Seattle.

"We have been looking for something for a long time," said Xiaohui Fan, an Arizona University researcher and chief author of a new job, in the Hubble Space Telescope report. "We do not expect to find many quasars in the visible universe that are more prominent than that!"

Several powerful ground telescopes and Hubble Space Telescope have gathered observations of this object, now called J043947.08 + 163415.7. The brightness of the quasars is provided by a super-black black hole: the material of the JS-surrounding gas disc falls into it, infusing and spreading radiation with different wavelengths, the report said. Quasar is probably shifted when the universe was not a billion years old but part of that light reaches Earth only now. The new observations show that the black hole that delivers quasar energy is several hundred million times more massive than the Sun.

Despite this brightness, the quasar is so distant that it is not a coincidence. The galaxy between Earth and the quasi-gravitational lens, quasi-light shifts around the galaxy, and we see a bigger picture: the quasar seems three times taller and 80 times lighter than it would otherwise be, researchers said in the report. The quasar is only visible because the galaxy that causes gravitational lensing is pale enough to not shine from the ultra-distant quasar light.

Yours sincerely: NASA, ESA, H. Fan (University of Arizona) For more research on the quasar that also creates 10,000 stars a year, you can learn more about this remarkably but significant time from the history of the first stars and galaxies . shaping our now visible universe. More and more telescopes join the search

"This discovery is amazing and important; For decades, we thought that such lenses were a very common phenomenon in the early universe, but so far it is only the first open, "said Fabio Packouci, a researcher at Yale University, co-author of this work, and principal author of another quasi- the Keck Observatory. , "He instructs us how to look for" fantastic quasars "- which are but are not yet discoverable.

"Our theoretical studies predict that a significant number of such" fantastic quasars "are not visible," adds Pucci. "If they are so many, this can lead to our understanding of the events immediately after the Great Revolution of the bombs and even change the approach to the mass growth of these cosmic monsters."
