Astronomers discover 83 dark holes on the planet's edge

A team of international astronomers has been looking for old black holes – and they have been hitting the motherlode, scoring 83 previously unknown cavities.

The universe is full of huge black holes, big blocks of the humble, black hole, which includes millions or millions of sunshine times. These big cosmic creatures have a huge impact on the earth, so you often find black holes above that which hide out at the center of the stars, marked by billions of stars . That's exactly what happens in our home draw on the Milk Way.

To find out that they are zooming out in distant parts of the world, you have to light a light to tear gas that is moving around them. Because we won't see a black hole, but we'll see the light, we see these powerful wells as “quasars”. Below a telescope rubbish they may be more like stars – they are quite clear – but scientists think their light comes from gas falling to a black hole.

The Japanese team turned the powerful power "Hyper Suprime-Cam", who drove it to Telescope Subaru in Hawaii, attacking dark dark cosmic corners, examining the air over five years. By examining the pictures, they have been able to choose convincing candidates from the dark. In particular, the way they experiment with numbers of elegant black holes that look like those we see today brings precision to their source.

Having identified 83 applicants the team used an international set of telescopes to confirm their findings. The quasars they sent out from the world were very early, about 13 billion years away. Practically, that means that the researchers are looking into the past, at things less than a billion years after the Big Bang.

"It is amazing that we were able to create such big things as soon after the Big Bang," said Michael Strauss, who contributed the paper, in a press release.

Scientists are not sure how black holes are formed in the early world, so it is possible to find new search routes to find out how far back in time. In particular, the researchers discover the probability of what appears to be less than they had expected. The properties of that particular hollow, HSC J124353.93 + 010038.5, were reported in The Astrophysical Journal Letters in February.

“The quasars we found out will be an interesting topic to explore further with current and future resources,” Yoshiki Matsuoka, a leading researcher, said in recitation.
