The center of the Milky Way is one of the most interesting regions of the$\gamma$-ray sky because of the potential for indirect dark matter (DM)detection. It is also complicated due to the many sources and uncertaintiesassociated with the diffuse $\gamma$-ray emission. Many independent groups haveclaimed a DM detection in the data collected by the Large Area Telescope onboard the Fermi $\gamma$-ray Satellite from the inner Galaxy region at energiesbelow 10 GeV. However, an exotic signal needs to be disentangled from the datausing a model of known $\gamma$-ray emitters, i.e. a background model. We pointout that deep understanding of background ingredients and their mainuncertainties is of capital importance to disentangle a dark matter signal fromthe Galaxy center.

Are we really seeing dark matter signals from the Milky Way center?
