Black Hole Spewing Iron, Nickel in Powerful Jets

Essentially a so called black hole is spinning at relativistic speed around its axis allowing the axis to act as the ejection points and the likely real two points at which the event horizon is actually working and converting matter into photonic energy.  Incoming material is also likely drawn toward these super poles and become accelerated by the photonic energy.

In addition, the photonic energy will also decay to form elemental particles as well.  All this produces powerful jets in smaller black holes with high spin to say nothing of plenty of light.

In the meantime recall that the nickel and iron content is trace and little else is clearly indicated or it might have been mentioned.  This suggests the end products of intense fusion reactions and any higher fission possibilities.

Has a black hole mystery just been solved?

Writing in the journal Nature, a team of scientists said it found traces of nickel and iron in the powerful jets shooting out of black hole candidate 4U 1630-47, a small black hole just a few times the mass of our sun. It may help solve a scientific puzzle that has lingered for decades.

Astronomers have known for years that hyper-dense black holes shoot matter into the universe in high-speed streams known as relativistic jets. However, nobody knew exactly what type of material the jets were spewing.

"It was one of the unsolved questions about relativistic jets produced in the vicinity of black holes," said Avi Loeb, chair of the department of astronomy at Harvard University, who was not involved with the study. "What is their composition?"

Everyone was in agreement that the jets would contain electrons, which have a negative charge. But the jets did not have a negative charge overall. That suggested there was something else in there with a positive charge that canceled it out.

In addition, some models of the jets suggested they were shooting lightweight electrons and positrons away from the black hole and into the universe. Others thought the jets were made of much heavier normal matter.

"Until now, it wasn't clear whether the positive charge came from positrons, the antimatter 'opposite' of electrons, or positively charged atoms," study coauthor James Miller-Jones of the International Center for Radio Astronomy Research said in a statement. "Since our results found nickel and iron in these jets, we now know that ordinary matter must be providing the positive charge."

Because it takes a lot more energy to move normal matter than it would to move the lightweight electrons and positrons, the authors suggests that the high-speed jets are carrying more energy away from the black hole than was previously known.

The study also sheds light on another scientific debate - exactly where the jets emerge from. It has been unclear whether the jets are caused by the spin of the rotating black hole, or if they originate from the disk of matter that surrounds the black hole.

"Our results suggest it's more likely the disk is responsible for channeling the matter into the jets, and we are planning further observations to try and confirm this," Miller-Jones said in the statement.

To come to these conclusions, the researchers looked at both radio waves and X-rays that were emitted by black hole 4U 1630-47.

The first time they looked, the radio wave spectrum suggested the jets were not on, and the X-ray spectrum did not reveal anything unusual.

"The jets are not always on," Miller-Jones told the Los Angeles Times. "It depends a little bit on how fast the black hole is feeding."

But the second time the team looked, the radio waves seemed to indicate the jets were on. At the same time, the X-ray spectrum picked up the characteristic signature of iron and nickel that was off just a bit.

The scientists believe the signatures were slightly skewed because of a Doppler-like effect in space.

"Just like a sound wave gets higher as it moves toward you and lower as it moves away from you, we saw the same effect," Miller-Jones said. "The energy was shifted a little bit to higher energies when it was moving toward us, and lower when it was moving away from us."

One especially cool result of this effect is that it allowed the researchers to determine how fast the material in the jets were moving. Their finding? A whopping 123,000 miles per second, or about 66% of the speed of light.
