Abstract
One of the most exciting recent results in the field of dark matter indirect searches has been the discovery of an excess emission in gamma rays from the Galactic centre above the standard astrophysical background. We show that current hydrodynamic simulations, namely simulated Milky Way-like galaxies within the "Evolution and Assembly of GaLaxies and their Environments" (EAGLE) project, challenge the possibility to interpret the GeV excess as due to annihilation of dark matter particles in the halo if the Milky Way.
