Dark matter is the most likely source of excess of gamma rays from galactic center

In the recent past, space missions dedicated to the study of astrophysical signals in the high-energy spectrum revealed a series of enigmatic excesses not predicted by the theoretical models. In order to find an explanation for these anomalies, many solutions have been proposed. The most exciting hypothesis invokes the contribution of the elusive dark matter, the mysterious form of matter four times more abundant than baryonic matter, and of which scientists have so far detected only gravitation...
