Mysterious gamma rays coming from the center of the Galaxy, give rise to young neutron stars, living in the densest region of the core of the milky Way, not the decay of dark matter particles. To such conclusion for astrophysics, published an article in the journal Nature.
“At such a distance, the individual streams of gamma-rays arising from these dead stars will merge together and form a uniformly distributed signal, similar to the one that needs to occur in the decay of dark matter particles. This is supported by the fact that millisecond pulsars located near the Ground, are considered to be bright sources of gamma rays,” said Roland Crocker at the Australian national University in Canberra.
Dark matter — the invisible substance, the presence of which can be judged only by its gravitational influence, it does not interact with electromagnetic waves, i.e., does not emit, absorb or reflect any radiation. For a fraction of the ordinary matter is 4.9% of the mass of the Universe, dark matter is 26.8%. Most physicists today believe that dark matter may consist of weakly interacting heavy particles, so-called “vinow”.
In 2009, as it seemed then scientists, recently launched gamma-ray telescope, “Fermi” discovered the first traces of dark matter in the form of the mysterious excess of gamma radiation in the milky Way’s brightness is in the high-energy part of the spectrum was much higher than theoretically predicted values. As suggested then the scientists, the source of this radiation were the decays are experiencing “vinow”.
From the point of view of astrophysics, disprove this theory quite easily – it is necessary to show that gamma photons from the center of the milky Way fly us from point light sources which could be pulsars and other compact objects. Otherwise, if they are generated by decaying particles of dark matter, “excess” radiation will be distributed uniformly across the sky.
