The 8.2-meter Subaru telescope is located at the Mauna Kea Observatory in Hawaii. National Astronomical Observatory of Japan (NAOJ). Astronomers have discovered 83 quasars working from supermassive black holes from billions of years ago, in the first 10 percent of the modern age of the universe
. . "It is noteworthy that such massive dense objects could have formed so quickly after the Big Bang," said Michael Strauss, professor of astrophysics at Princeton University, and co-author of the study. "Understanding how black holes can be formed in the early universe, and how widespread they are, is a challenge for our cosmological models."
The data was collected by looking at distant objects that are about 1
3 billion light-years away from Earth. Since light takes time to go through this vast distance, watching the quasars is far away, as a review of the past 13 billion years. A large explosion occurred 13.8 billion years ago, so these observations show how the universe was in its infancy
To see quasars at that distance, an extremely powerful telescope was needed. Subaru Telescope is equipped with a tool called Hyper Suprime-Cam (HSC), which has a huge field of view at 1.77 degrees, which is seven times the area of the full moon. For viewing, the Hubble Space Telescope has a field of view of just 0.04 degrees, that is, many individual images need to be sewn together to form beautiful photos that we all love to see.
Using HSC, researchers were able to determine that among the 83 new quasars and 17 that were already discovered in the study area, there was about one supermassive black hole in the cubic hail light year. This means that if you cut the universe into cubes that were billions of light years on each side, then you would expect to find one supermassive black hole per piece.
The next goal of the team is to hunt for more black holes and hope it will emerge when our first supermassive black hole appeared in our universe.
