Fitting the Fermi-LAT GeV excess: on the importance of the propagation of electrons from dark matter
Thomas Lacroix
An excess of gamma rays at GeV energies has been detected in the Fermi-LAT data. This signal comes from a narrow region around the Galactic Center and has been interpreted as possi…

A possible link between the GeV excess and the 511 keV emission line in the Galactic Centre
Celine Boehm, Paolo Gondolo, Pierre Jean +3
The morphology and characteristics of the so-called GeV gamma-ray excess detected in the Milky Way lead us to speculate about a possible common origin with the 511 keV line mapped…
