This one QuasarThe bright object, which emits strong radiation in the form of radio waves, took 13 billion light-years to reach Earth.
With the help of the European Southern Observatory (ESO) Large Telescope (VLT) in Chile, the American Cake of Hawaii, and a very large array, this discovery will help scientists better understand the early universe and the first galaxies. . Radio waves from the quasar P172 + 18 were emitted at a time when the universe was only 780 million years old, 100 million years earlier than the previous record holder.
Quasars, first discovered in 1963, are extremely bright objects – the brightest in the universe – located in the center of some galaxies. Black holes. The black hole that powers the early quasar P172 + 18 is estimated to be 70 times the mass of the central black hole of our galaxy, 300 million times that of the Sun, and emits 580 times more energy than our entire galaxy. One of the greatest mysteries of astronomy is how there were such large black holes in a very small universe.
Like a black holeSwallowingAmbient gases emit large amounts of energy at different wavelengths, traveling at almost the speed of light and allowing scientists to detect the phenomenon, albeit in space and time. At radio frequencies only 10% of quasars glow.
The researchers, led by Eduardo Banados of the German Max Planck Institute for Astronomy and Kiara Matsukeli of the ESO, published their publications in The Astrophysical Journal and the Journal of Astronomy.
