Astronomers find 83 super massive black holes on the edge of the universe

A team of international astronomers are looking for ancient, super-massive black holes – and they hit the mother, finding 83 quasars unknown so far. , a daily black hole containing millions or billions of times more than our sun. These enormous cosmic beasts create enormous gravitational effects, so you often find supermassive black holes hiding in the center of the galaxies bent by billions of stars. This is exactly what happens in our Milky Way Home Galaxy.

In order to find them in the remote parts of the universe, you have to study the light of the gases that dissipate around them. Since we can not see a black hole, but we can see the light, we denote these powerful light sources as "quasars". On the telescope's eyepiece, they could look more like stars ̵

1; they are extremely bright – but scientists believe that their light comes from gases falling into a black hole. Cam ", mounted on the Subaru telescope in Hawaii, to the darkest angles of space, watching the sky for five years. By studying the pictures, they managed to choose potential candidates for quasars of darkness. It should be noted that their method of exploring the populations of super massive black holes that are similar in size to those we see in today's universe has given us a window of their origin. telescopes to confirm their findings. The quasars they dug are from the earliest universe, about 13 billion light-years away. In practice, this means researchers are looking at objects in the past – less than a billion years after the Big Bang. Michael Strauss, who co-authored the newspaper in a press release. Scientists are not sure how the black holes have formed in the early universe, so the ability to find them so long provides new research opportunities. In particular, researchers find a quasar with much lower brightness than they expected. The characteristics of this particular quasar, HSC J124353.93 + 010038.5, were reported in The Astrophysical Journal Letters in February.

"The quasars we've found will be an interesting subject for further observations with current and future facilities," said Yoshiki Matsuoka, lead researcher in a statement.
