Researchers have discovered dark matter in the Milky Way.


Researchers have discovered dark matter in the Milky Way.

If we divide 100% of the universe,then we come to know that 85% is of Dark Matter, we do not know much about Dark Matter,and today there is a mystery about Dark Matter.  Dark matter was believed to be responsible for the kind of mysterious electromagnetic signals found in galaxies, but a new research has rejected it.  The first researchers expected this, behind the mysterious electromagnetic signals is dark matter, it is caused by dark matter.

The universe has dark matter, which cannot be seen, because it does not absorb, reflect or emit light, the effect of dark matter is present on other matter. We can understand this, such as gravitational forces. To explain the gravitational forces holding together we need dark matter.

Physicists have suggested that dark matter is a closely related pair of neutrinos, called sterile neutrinos, neutrinos — sub-nuclear particles with no charge, that are released during nuclear reactions inside the Sun. The neutrino possesses a small amount of mass, usually a particle of this mass is not explained by physical standard models.  Physicists have suggested a sterile neutrino, that it is an imaginary particle, that dark matter may be responsible for its mass.

Ben Safdi, co-author and assistant professor of physics at UM, says that our researchers should be able to detect sterile neutrinos. Researchers scan the galaxies to detect dark matter, to understand this electromagnetic radiation in the form of X-ray emission. In 2014, a seminal work discovered additional X-ray emission from nearby galaxies and galaxy clusters, with Ben Safdi stating that the emission was consistent with the black matter decay of sterile neutrinos  Is generated.

Objects in the Milky Way were taken by the XMM-Newton Space X-ray Telescope, yet no evidence has been found from the raw data as to what a sterile neutrino is, whether it contains dark matter. Space-based X-ray telescopes, such as the XMM-Newton telescope, point to dark-matter-rich environments, in the form of X-ray signals, to discover this faint electromagnetic radiation. The discovery, made in 2014, is named X-ray emission “3.5 kV line”, kV meaning kilo-electronvolts, where the signal appears on X-ray detectors. Using 20 years of archival data, taken by the XMM-Newton Space X-ray Telescope, researchers have discovered a “3.5 keV line” in the Milky Way that physicists had hoped to find around dark matter galaxies. Pass collects, analyzes looked at nearby galaxies and galaxy clusters, so each of those images would have captured some columns of the Milky Way dark matter halo. 

Rod of Berkeley Lab says that we see that there must be some flow of dark matter everywhere from the Milky Way halo, because the location of the solar system is in the galaxy, and we have also taken advantage of this fact, we know the study  Well, we live in a halo of dark matter. Christopher Desert, a study co-author who is a physics researcher and Ph.D. The UM student said that in galaxy clusters where the 3.5 kV line is observed, they also have large background signals, which act as noise in observations, and can make it difficult to pinpoint specific signals, which are dark.  May be related to substance.

XMM-Newton has taken images of different stars and individual objects in the Milky Way, taken, in these images, the researchers mask objects of original interest, allowing for a very easy dark environment, including dark The radiance of the decay of matter was discovered, allowing researchers to test such observations for an unprecedented level of sterile neutrino dark matter, combining over 20 years. If indeed sterile neutrinos were dark matter, and their decay emits a 3.5 kV line, then Safdi and his fellow researchers should observe that line in their analysis, but right now Safdi and his fellow researchers must find sterile neutrino dark matter, No evidence was found for.
