There are the physicist and researchers from the German and Hungary Team headed by Professor ZoltanFodor from the University of Wuppertal, Eotvos University in Budapest and Forschungszentrum Julich carried out its estimations on Julich’s supercomputer JUQUEEN.
“The dark matter is a hidden type of matter that till now has just disclosed itself through its gravitational effects. What it comprises of remains an absolute mystery,” explaind co – author Dr, Andreas Ringwaid, who is from DESY and who introduced the present research. Evidence for the existence of such sort of matter comes from, among other items, from the astrophysical observation of galaxies that rotate too far swiftly to be held together only by the gravitational pull of the visible substance.
High – accuracy estimations utilizing the European satellite ‘Planck’ reveal that almost 95 percent of the entire mass from the universe comprises of dark matter. All the planets, stars, nebulae as well as other objects in space that are prepared from conventional matter account for not more than 15 percent of such mass of the universe.
“Such adjective dark does not just imply that it does not release visible light,” says Ringwald. “It does not seem to give off any other wavelengths either – its interaction with photons must be highly weak indeed.” For years, physicists have been hunting for elements of such novel sort of matter. What is clear is that such particles must rest beyond the Standard Model of particle physics and while that model is highly successful, it presently just illustrates the traditional 15 percent of all the matter in cosmos.
From theoretically feasible extensions to the Standard Model Physicists not only expect an intense understanding of the space, but also focus clues in what energy range it is commonly worthwhile searching for dark – substance candidates.
The results indicates that is axions are able to prepare the bulk of dark matter, they must possess a mass of 50 to 1500 micro – electronvolts, showcased in the customary units of particle physics, and hence be up to ten billion times smaller than the electrons. It would need every cubic centimetre of the universe to comprise on average ten million such ultra-lightweight elements. Dark matter is not extended out evenly in the universe, but creates branches and clumps of a web-like network. For such reason, the local region of the Milky Way must comprise about one trillion axions per cubic centimetre.
With the supercomputer, such estimations now offering physicists with a concrete range in which their hunt for axions is likely to be most promising. “The results we are showcasing will probably result in a race to identify such particles,” says Fodor. Such discovery would definitely deliver an answer to reasons for strong interaction with respect to time reversal.
