Astronomers have discovered the brightest “wandering” black hole

A group of researchers under the leadership of the French astrophysics Olivier from the University of Toulouse found in the constellation of Bootes the potential black hole, freely “wandering” in space. Due to the distance it poses no threat to Land, but, nevertheless, is a more than interesting study.

Heavenly body, whose existence is indicated by the data from telescopes Chandra and XMM-Newton, is on pretty solid even on a cosmic scale, the distance from us is 4.5 billion light years — and plenty of it, according to the calculations of experts, about one hundred thousand times the mass of the Sun, while this indicator on the “crossroads” between massive and supermassive black holes.

As expected, in the past, the object, dubbed XJ1417+52 once was the center of a small galaxy. However, as a result of a disaster black hole “went to pilgrimage”, and is now circling near the galaxy GJ1417+52, the study of which experts and made an unexpected discovery.

XJ1417+52 is not the first choice for the recognition of “wandering” black hole, moreover, it is not the closest and not the biggest of them. However, at the time when she saw the scientists, the potential black hole ten times more intense radiated x-rays than any previously known candidate for a facility of this type. As expected, the astronomers were fortunate to witness the moment when a black hole absorbs one near her, and caused a burst of brightness.

Experts do not exclude that “wandering” black holes, albeit smaller, can be in the relative vicinity of our galaxy. However, until now even the existence of such objects in the Universe is considered to be proven only theoretically — similar celestial bodies are still in the status of “candidates”.

The scientific work of scientists accepted for publication edition of the Astrophysical Journal.
