Abstract: We discuss prospects for detecting/constraining annihilating dark matter models from astrophysical and cosmological observations in the light of recent measurements of anomalous cosmic-ray positron and electron fluxes.
In particular, we focus on high-energy neutrinos from the Galactic center and diffuse extragalactic gamma-rays, and show that they give stringent bounds on annihilating dark matter models.
