Searching for neutrinos from dark matter annihilations in (dwarf) galaxies and clusters with IceCube — •Meike de With¹ and Elisa Bernardini² for the IceCube collaboration — ¹Institut für Physik, Humboldt-Universität zu Berlin, D-12489 Berlin, Deutschland — ²DESY, D-15735 Zeuthen, Deutschland

In many models, the self-annihilation of dark matter particles will create neutrinos which can be detected on Earth. An excess flux of these neutrinos is expected from regions of increased dark matter density, like (dwarf) galaxies and galaxy clusters. The IceCube neutrino observatory, a cubic-kilometer neutrino detector at the South Pole, is capable of detecting neutrinos down to energies of few 10 GeV and is therefore able to constrain the self-annihilation cross section as a function of the mass of the dark matter particle. In this talk, the current status of the search for neutrinos from dark matter annihilations in (dwarf) galaxies and galaxy clusters with IceCube will be discussed.
