Description
The excess of GeV-scale photons observed by the Fermi
telescope in the direction of the Galactic Centre is strikingly
similar in both rate and spatial distribution to the expectations for
annihilating dark matter. I'll discuss dark matter models that can
reconcile the Fermi signal with the lack of signals from direct
detection and collider experiments. If the Fermi signal is indeed due
to dark matter, then the Milky Way's super-massive black hole should
give rise to an additional point-source like contribution to the gamma
ray signal. The canonical expectation for this point-like source is
incompatible with Fermi measurements of the Galactic Centre, and I'll
talk about possible astrophysical and particle consequences of this
observation.
