Russia, Finland and the U.S. Researchers have put an obstacle on the theoretical models of dark matter particles by analyzing data from the astronomical observations of active galactic nuclei. New conclusions provide a joint incentive for research groups around the world who are trying to circumvent the secret of black matter: There is no certainty of what it is made of. Paper was published in Journal of Cosmology and Astroportical Physics. New Search Provides Incentives To Crack Dark Matter Mystery.
The question of what particle forms the particle is a key for modern particle physics. Despite the hope that the dark matter particles will be discovered in the Large Hadron Collider, it did not happen. The nature of the black body was rejected by the then mainstream hypothesis. Miscellaneous comments indicate that dark matter is present, but apparently there is something other than particles in the standard model. In this way physicists will have to consider further options which are more complex. The standard model needs to be expanded. Candidates have hypothetical particles for inclusion, which can be the mass of electrons from 10 to 10 times the mass of the electron. That is, the most massive spec particles are 40 lightweight on a larger scale compared to the mass.
A theoretical model considers dark matter made of ultra-light particles. It provides an explanation for many astronomical observations. However, such particles will be so light that they will have very poor interaction with other cases and light, which will make them very difficult to study. It is almost impossible to keep such a particle in a laboratory, so researchers tend to astronomical observations.
“We are talking about dark matter particles which are 28 sequences of magnitude compared to electrons. This perception is important for the model that we have decided to test. The gravitational contact is that which deceives the presence of dark matter. If we explain all the black matter masses in terms of ultraviolet particles, then it means that there is a tremendous number of them. But with the light in the form of particles as these, the question arises: How do we protect them from achieving effective mass due to quantum improvement? The calculation shows that a possible answer would be that these particles interact with the photon weakly – that is, with electromagnetic radiation. It provides a very easy way for them to study: By observing electromagnetic radiation in space, “said Sergey Trotsky, is the paper’s principal author and researcher at the Institute of Nuclear Research of the Russian Academy of Sciences.
When the number of particles is very high, instead of individual particles, you can consider them as the area of density that crosses the universe. This field is located consistently on domains, which are in the shape of 100 parsecs or approximately 325 light year sequences. The oscillation period determines the mass of the particles. If the model considered by the authors is correct, then this period should be approximately one year. When polarized radiation passes through such an area, the plane of radiation polarization shakes with the same period. If such periodic changes are in fact, astronomical observations can reveal them. And the duration of the period – a terrestrial year – is very convenient, because many celestial objects are seen in many years, which is sufficient for change in polarization to reveal itself.
The authors of the paper decided to use the data from earth-based radio telescopes, because they often return to the same celestial objects during a cycle of observations. Such telescopes can inspect remote active galactic nuclei – areas of superhit plasma near the centers of galaxies. These regions emit excessive polarized radiation By observing them, a person can track the change in polarization angle over many years.
“At first it seemed that signs of individual celestial objects were showing sinusoidal oscillations. But the problem was that the sign duration is to be determined by the dark matter particle mass, which means that it should be equal to each object. There were 30 items in our sample. And it may be that some of them oscillate due to their own internal physics, but anyway, periods were never the same, “Trotsky walks. “This means that the interaction of our ultraviolet particles with radiation can be well interrupted. We are not saying that such particles are not present, but we have demonstrated that they do not interact with the photon, put an obstacle on the available substances which describe the structure of the dark matter. “
“Just imagine how exciting he was! When you come to the theoretical physicists one day, and you are useful for understanding our high-precision and high angular resolution polarization measurement, suddenly the nature of the black body, then spend enthusiastically studying. Studies and Laboratory Director at the Moscow Institute of Physics and Technology and Lebedev Physical Institute of the Russian Academy of Sciences.
In the future, the team is planning to explore the manifestations of the huge deep particle particles proposed by other theoretical models. This will require working in various spectral categories and using other observational techniques. According to Trotsky, barriers on alternative models are more stringent.
“Right now, the whole world is engaged in the search of dark matter particles. This particle is one of the great mysteries of physics. To date, no models have been accepted as preferred, well-developed or more appreciable in relation to the experimental data available. We have to test them all. Incongibly, dark matter is “dark” in the sense that it rarely talks with anything, especially with light. Obviously, in some scenarios this light may have little effect on the waves. But the other scenario does not predict any kind of interaction between our world and the dark matter, which is apart from mediating by gravity. It will be very difficult to find its particles, “Trotsky’s conclusion is.
