PAMELA and ATIC recently reported an excess in e± cosmic rays. We show that if it is due to Dark Matter annihilations, the associated gamma-ray flux and the synchrotron emission produced by e± in the galactic magnetic field violate HESS and radio observations of the galactic center and HESS observations of dwarf spheroidals, unless the DM density profile is significantly less steep than the benchmark NFW and Einasto profiles.

• History of dark matter (2018, unknown): “…received much attention as a possible signal of annihilating dark matter, this possibility is now strongly constrained by a variety of arguments (Bertone et al., 2009; Galli et al., 2009; Slatyer, Padmanabhan, and Finkbeiner, 2009), and plausible astrophysical explanations have also been…”
