Problem description:
Is gamma ray the strongest ray in the universe? If not, what is the strongest ray in the universe?
Analysis:
Haha, I finally met an astronomy fan. As far as I know, yes,
Gamma-ray bursts are thought to be shouts that resound through the universe with the birth of black holes.
Her energy is almost unimaginable and is one of the most puzzling phenomena in the universe.
A Swift satellite was launched on June 5438+065438+ 10, 2004, which was specially used to determine the source and path of gamma-ray bursts.
At present, through the latest observation data of Swift,
Scientists have made some remarkable progress in understanding gamma ray bursts.
In particular, the understanding of the mysterious instantaneous short-term gamma ray burst has taken a big step forward.
According to the observed high redshift ray burst in early BIGBANG,
And the huge X-ray flare produced in the later period of gamma ray burst.
Some scientists in the United States recently suggested that,
The mysterious and powerful gamma ray burst in the depths of the universe may be the product of the "hot dance" of black holes.
Patan, a scientist at the Massachusetts Institute of Technology, and others recently published an article on the website of Science magazine in the United States.
Published an article saying that they are interested in black holes and their "partners"-in a residual state.
Studied these stars. They put the interaction between these two celestial bodies,
Described as dancing the "Cosmic Tango".
Scientists say that the stars in the residual state actually appear in rings.
Completely passive in the "dance" with black holes. In this radical "dance",
Coiled magnetic lines of force surround two celestial bodies, such as winding arms. A black hole and its "partner"
Turning faster and faster, the remnants of the surrounding stars continue to absorb huge energy from the black hole, and the "heat" is dispersed.
Finally, the remnants of the ring star are pulled tightly to the black hole and go to the end of destruction.
This "cosmic tango" is followed by * * *, and the rest is a "panting" black hole.
"Cosmic Tango" is of course only a description, and scientists just use it to express their achievements more vividly. Patan and others are most interested in the mechanism of energy exchange and divergence between two celestial bodies in this process. They specially built a model for this purpose, and found that two celestial bodies will produce a directional jet gamma ray along the direction of the black hole's rotation axis during the process of "dancing". However, this is only a very small part of the "Cosmic Tango". During the interaction between two celestial bodies, most of the energy equivalent to 100 times of gamma ray bursts is scattered into space in the form of gravity waves through the remnants of stars.
Scientists point out that the model of "Cosmic Tango" has one advantage, which can explain the contradictions found in previous astronomical observations. Although the rotating black hole is considered as a possible source of gamma rays, its energy is generally emitted everywhere at will, and the model observation shows that the energy of gamma rays is generally directional. Scientists believe that the "Cosmic Tango" model can solve this paradox.
According to this model, the star residue undergoes a brief interaction with the black hole, rather than being sucked in by the black hole at once. More crucially, this model also believes that star residues absorb energy from black holes and redirect the absorbed energy in the form of gamma ray bursts through their own rotation, just like an efficient catalytic converter.
However, Patan and others said that their model is only theoretical and needs to be tested by future astronomical observations. Their paper on this model will soon be published in the American journal Science.
I really want to make some friends with astronomy lovers.
