Description
Gamma-ray line signatures can be expected in the very-high-energy () domain due to self-annihilation or decay of dark matter (DM) particles in space. Such a signal would be readily distinguishable from astrophysical -ray sources that in most cases produce continuous spectra that span over several orders of magnitude in energy. Using data collected with the H.E.S.S. -ray instrument, upper limits on linelike emission are obtained in the energy range between and for the central part of the Milky Way halo and for extragalactic observations, complementing recent limits obtained with the Fermi-LAT instrument at lower energies. No statistically significant signal could be found. For monochromatic -ray line emission, flux limits of and are obtained for the central part of the Milky Way halo and extragalactic observations, respectively. For …
