The targets of interest include the Virgo and Coma galaxy clusters, the Andromeda galaxy, and several dwarf galaxies. We obtain upper limits on the cross section as a function of the weakly interacting massive particle mass between 300 GeV and 100 TeV for the annihilation into bb¯, W+W−, τ+τ−, μ+μ−, and νν¯. A limit derived for the Virgo cluster, when assuming a large effect from subhalos, challenges the weakly interacting massive particle interpretation of a recently observed GeV positron excess in cosmic rays.en© 2013 American Physical SocietyIceCube search for dark matter annihilation in nearby galaxies and galaxy clustersJournal article002013433110.1103/PhysRevD.88.1220010003286046000022-s2.0-8489092864916602
