Discover hundreds of black holes in the universe
French astrophysicists have identified hundreds of quasars, meaning the supermassive black hole emits strong energy hidden in sandy galaxies. These black holes are known to exist theoretically, but so far have not been observed.
The research team at Paris Diderot University, the National Center for Scientific Research and the French Grain Energy Commission, used NASA's Spitzer and Chandra space telescopes to identify them.
The identification was made by observing about 1,000 distant galaxies, about 9 to 11 billion light-years from Earth, to prove there are hundreds of millions of other black holes in the universe.
Spitzer satellite infrared observations have demonstrated that 20% of observed galaxies emit an extraordinary amount of infrared radiation. When superimposing images of all galaxies on each other, the researchers discovered a signal that demonstrated the presence of quasars inside these galaxies.
These newly discovered quasars will allow understanding of the formation of galaxies in the distant universe, especially proving that galaxies that have created stars simultaneously with black holes are growing until Devour all these stars.
