Mysterious X-ray cloud had scientists thinking it’s a mass gathering of astral black holes

 

The eerily cryptic cloud has elicited speculation by astronomers as to its source, though the answer has eluded them.

Professor Chuck Hailey of University of Columbia in New York, the study’s author says,  “This is something that has never been seen before, I only wish we knew what it is that we discovered. We have quite a few theories of what it could be, but none of them fits the facts, so at this point it’s something of a mystery.”

A huge X-ray cloud was discovered, while observing a section, 30 light-years wide in the immensely colossal black hole at the center of the Milky Way galaxy, by an international team of scientists, with the use of the NuSTAR X-ray Observatory.

 

The enormous epicenter encompasses an unequally massive populace of planetary substances, which includes a great number of immense hot young stars and burnt out dead stars.

The X-rays may be created by an oddly enormous population of white dwarf stars, the stellar carcasses of Sun-like stars after they have ceased shining.

“White dwarfs can emit intense high energy X-rays, and they are common in the universe because there are plenty of stars similar to our Sun.  Although if they’re the explanation, they’re a bit unusual, because it would imply these white dwarfs are somewhat more massive than other white dwarfs seen elsewhere in the galaxy. So it’s very strange to find all these very heavy white dwarfs close to the super massive black hole,” says Hailey.

Otherwise, the X-rays might be fashioned by another kind of dead star named pulsar. The greatly dense remnants of a star far more gigantic than the Sun, which shattered as a supernova when it depleted its fuel and stopped shining.

“If this is the explanation, then there must be a very large population of them around the super massive black hole, and in fact many theorists have speculated that there should be large numbers in that vicinity,” Hailey said.

According to Prof. Hailey, the most exhilarating possibilities are astral mass black holes, which are formed when even more massive stars that form pulsars go supernova and expire.

Nonetheless, the X-rays could just be easily created by the immense gigantic black hole itself.

“We know black holes in the centers of galaxies produce jets of particles, and these very energetic particles could collide with gas in the vicinity around the supermassive black hole, producing very high energy X-ray emissions,” said Hailey.
