Description
The abundance of dark matter in the Universe could be explained by heavy dark matter. Heavy dark matter decay in massive astrophysical objects could produce highly energetic neutrinos that can be detected at neutrino telescopes. We present an analysis that searches for dark matter decay in extragalactic sources, using 9 years of IceCube data. The sources considered are galaxy clusters, dwarf galaxies, and the Andromeda galaxy. We use a well established neutrino event selection criteria for neutrino candidate events from the northern hemisphere. We focus on heavy decaying dark matter with masses from 10 TeV to 10 PeV and consider several benchmark decay channels into pairs of Standard Model particles. In this contribution, we present the latest analysis status and sensitivities calculated using the individual sources and by stacking the sources within the same source class.
