Signs of stray black hole discovered in the Milky Way as researchers reveal new method to search for the elusive objects

It is believed that there may be a black hole as much as 100 million to 1 billion in the milky way – but because light cannot escape from its context, these things are very difficult to spot.


Researchers have now launched a new method that could change search black hole.

By analyzing the movements of the mysterious gas clouds, the team found evidence of a black hole hidden in our Galaxy, and they say that the method can be used to find the others.

Researchers at Keio University was initially established to observe molecular clouds around supernova remnant W44 sit 10,000 light years from Earth.

Using a telescope in Chile and the feast in the 45-m Radio telescope at Nobeyama Radio Observatory, both operated by the National Astronomical Observatory Japan team plans to examine the amount of energy transferred from the supernova to gas molecules surrounding it.


But they found signs of a black hole ' wild ' on the edge the rest of the supernova.

The researchers found dense molecular clouds, nicknamed "the bullet," with a strange pattern of movement.

The cloud has a speed of more than 100 km/s-faster than the speed of sound in the interstellar space with more than doubled.

On top of this, the cloud is moving backwards against the rotation of the milky way.

The researchers investigated the mysterious clouds using a telescope of the two, and finds that he has tremendous kinetic energy, causing it to look as if it was to jump from the edge of the W44.

"Most of the bullets have a growing movement with speeds of 50 km/s, but the tip of the ball has a speed of 120 km/s," said graduate student Masaya Yamada.


In one scenario, called ' a ' models, the blast past the shell gas evolved from a supernova remnant around the black hole.

The black hole pulls gas near it, prompting an explosion of gas accelerates towards the Earth, after the shell passed through a black hole.

Researchers estimate that the black hole has a mass of about 3.5 times more massive than the Sun, or larger.

In the second scenario, called ' model ' describes a black hole high speed flow stormed through dense clouds of gas.

When this happens, the gas is pulled by gravity from the black hole forming.

This explanation, the black hole will be at least 36 times greater than the Sun.

But they are not yet sure which scenario is usually more.

"We found a new way to detect black holes get lost, "he said Oka, a professor at the University.

Moving forward, the team will further investigate the proposed scenario to find more evidence for a black hole by using a radio interferometer, such as the Atacama large millimeter/submillimeter Array (ALMA).
