Abstract

During the last decades, increasingly precise astronomical observations of the Galactic Centre (GC) region at radio, infrared, and X-ray wavelengths laid the foundations to a detailed understanding of the high energy astroparticle physics of this most remarkable location in the Galaxy. Recently, observations of this region in high energy (HE, 10 MeV–100 GeV) and very high energy (VHE, > 100 GeV) γ -rays added important insights to the emerging picture of the Galactic nucleus as a most violent and active region where acceleration of particles to very high energies – possibly up to a PeV – and their transport can be studied in great detail. Moreover, the inner Galaxy is believed to host large concentrations of dark matter (DM), and is therefore one of the prime targets for the indirect search for γ -rays from annihilating or decaying dark matter particles. In this article, the current understanding of the γ -ray emission emanating from the GC is summarised and the results of recent DM searches in HE and VHE γ -rays are reviewed. [ABSTRACT FROM AUTHOR]
