| Résumé : | Dark matter could decay into Standard Model particles producing neutrinos directly or indirectly. The resulting flux of neutrinos from these decays could be detectable at neutrino telescopes and would be associated with massive celestial objects where dark matter is expected to be accumulated. Recent observations of high-energy astrophysical neutrinos at IceCube might hint at a signal produced by the decay of TeV to PeV scale dark matter. This analysis searches for neutrinos from decaying dark matter in nearby galaxy clusters and galaxies. We focus on dark matter masses from 10 TeV to 1 EeV and four decay channels: νν̄, τ+τ−, W+W−, bb̄. Three galaxy clusters, seven dwarf galaxies, and the Andromeda galaxy are chosen as targets and stacked within the same source class. A well-established IceCube data sample is used, which contains 10.4 years of upward-going track-like events. In this contribution, we present preliminary results of the analysis. |
