Discovering dark matter is one of today's biggest challenges of particle physics and cosmology. In particular, indirect dark matter detection aims to discriminate the flux of final stable particles —gamma rays, charged cosmic rays and neutrinos — produced by particle dark matter annihilation or decay from the dominant background induced by astrophysical processes.

I will present the state-of-the-art of dark matter searches at the Galactic centre, one of the most promising targets for dark matter identification. Recently, a spatially extended excess of gamma rays collected by the Fermi-LAT has been discovered in the inner region of our Galaxy. I will discuss the major results in this context and scrutinise the most promising interpretations in order to shed light onto the origin of this yet unknown extra-emission at the Galactic centre.
