Leiden University may find dark matter signal in X-rays




A group of European researchers led by the University of Leiden has a signal detected in the spectrum of x-rays that may be attributed to dark matter. The signal corresponds to what was previously predicted.

The researchers have not yet published their findings in a scientific journal, but already have a first version of their manuscript on arXiv put . It allows the research team, led by the University of Leiden, that they have discovered in the galaxy cluster Perseus and Andromeda galaxy signs that may indicate the existence of dark matter. Perseus could, if the theory is correct, should be rich in dark matter.

According to scientists, the signals were observed in radiation from the X-ray spectrum. The observed signals were stronger in the center of objects and weaker at the edges, which corresponds to predictions made earlier for the presence of dark matter. Then the scientists tried to verify it appeared that prevent such signals in the Milky Way their findings.

Dark matter is matter of which the effect of gravity is been shown, but may be further not be measured by conventional means. This is because the particles do not interact with light. Scientists already adhere long been engaged in finding out the properties of dark matter. Until now there were only found evidence in measurements, but no hard evidence. Or Leiden University has now found actually dark matter will emerge from future research.
