Searching for neutrinos from dark matter annihilations in galaxies and galaxy clusters with IceCube — •Meike de With¹, Elisa Bernardini², and Alexander Kappes³ for the IceCube collaboration — ¹Institut für Physik, Humboldt-Universität zu Berlin, D-12489 Berlin, Deutschland — ²DESY, D-15735 Zeuthen, Deutschland — ³Erlangen Centre for Astroparticle Physics, Friedrich-Alexander-Universität Erlangen-Nürnberg, D-91058 Erlangen, 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 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 the order of 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 galaxies and clusters with IceCube will be discussed.
