Scientists from the USA, New Zealand, Australia and Germany found evidence that the type of star formation near the center of the Milky Way, and not dark matter, is responsible for the emission of gamma rays.
In the past few years, physicists have argued about the topic of large gamma-ray emissions from the galactic center. Many believed that there should be a connection with dark matter particles (WIMP), colliding with each other or with ordinary matter. But in a recent study, scientists state another source, questioning dark matter as a cause of emissions.
Scientists reviewed information from the Fermi space telescope, which has been in orbit for the last ten years. They noticed that gamma rays actually reflect the distribution of stars near the galactic center. Their form was created in the form of "X", and not a sphere, as was expected in the case of the variant with dark matter. The new model allowed us to show that the collection of millisecond pulsars was a more likely explanation of the situation. Their rays merged and created a signal, which was initially taken for the manifestation of dark matter.
The researchers noted that their result provides the most likely explanation for the nature of gamma-ray signals, but this is not as interesting as the dark matter option. Usually it manifests itself in the form of light curves or strange behavior of objects.
