Galactic Center Gamma-Ray Excess As Imprint of Dark Matter

Probably, annihilation of atoms from magnetic monopoles (2.4 GeV) and their transitions in the Lyman series (1.8, 2.1, and 2.25 GeV) could result in a gamma-ray excess in our galactic center, which was observed by the Fermi observatory. Monopoles of GeV energies can form in the magnetospheres of magnetars and be blown out of them. At the galactic scale, atoms from magnetic monopoles (g+g‒) are part of dark matter.
