[November 15 AFP] The paper that there is a possibility that heavy atoms, such as iron, are contained in the substance which blows off from a black hole in the shape of a jet by ultra high-speed was announced by English science journal Nature (Nature) on the 13th.
? astronomers have been pulled to the thin beam of the substance which is the most powerful phenomenon in the universe and which blows off from a black hole in interest over tens of years.
? — this jet understands that the electron which are particles electrified in negative (minus) is contained.
But it being a mystery was that the whole jet is not charged negatively.
this offsets a negative electric charge — right (plus) — it was charged — “some” — the body meaning being there.
?, then Commonwealth Scientific and Industrial Research Organisation () [ Commonwealth Scientific and Industrial Research Organisation and ] The research team of CSIRO is the European Space Agency (). [ European Space Agency and ] Using the compact radio interferometer (Compact Array) of X ray observation satellite XMM Newton (XMM-Newton) of ESA, and eastern Australia, it traced that “something” was regarded as atoms, such as iron and nickel.

From the small black hole called “4U1630-47”, two or more atomic spectra were observed in the jet currently emitted at the rate of 2/3 of the velocity of light.
The source of this jet is regarded as the accretion disc.
An accretion disc is a belt of the hot gas which surrounds the suction mouth of a black hole.
The importance of discovery of ? this time is at the point which showed that a black hole carried out not only destruction but creation.
? black hole makes space re-circulate through a substance or energy.
The jet is playing a role in deciding when and where star formation of the Galaxy occurs.
Mr. Tasso Tzioumis of ?CSIRO says in Press Releases, “The jet emitted from a supermassive black hole helps to decide the fate of the Galaxy.”
“Therefore, the jet thinks that he would like to further deepen an understanding about the influence which it has on the surrounding environment.”
Since the atom of ? iron has one about 100,000 times the mass of an electron, compared with the light particles which he follows at the same speed, a lot of energies will be carried to Haruka.
By the collision with the substance in ? interstellar space, the research team says that the gamma ray and the electron may have occurred.
