Radiation can result from the interaction of uncertain sources.
Astronomers at the American space Agency NASA has published recent discoveries made by the space telescope Fermi. Scientists have found traces of dark matter in the galaxy Andromeda.
Scientists believe that the radiation can result from the interaction of uncertain sources, one of which is dark matter, which makes up most of the universe. In particular, at NASA believe that the excess of gamma radiation in the center of the galaxy are a consequence of the collapse, colliding with each other winow, which represent a massive particle with weak interaction. It should be noted that previously, a similar signal, scientists have recorded in the center of the milky way.
“We believe that dark matter is concentrated deep in the center of the milky way and other galaxies, so discovery of such a compact signal is a very intriguing finding. M31 can be the key to understanding the structure and Andromeda, and the milky way,” explained a leading astrophysicist, National center for scientific research and Institute of astrophysics and planetology in Toulouse Pierrick Martin (Pierrick Martin).
Another explanation of the phenomenon is the concentration of the pulsars in the center of the galaxy. A rotating neutron star whose mass is twice the mass of the Sun and are among the most dense objects in the Universe are gamma-ray sources. The scientists intend to test this theory by studying x-ray and radio wave radiation
