The Case for a 700+ GeV WIMP: Cosmic Ray Spectra from PAMELA, Fermi and ATIC
Ilias Cholis, Gregory Dobler, Douglas P. Finkbeiner +2
Multiple lines of evidence indicate an anomalous injection of high-energy e+- in the Galactic halo. The recent fraction spectrum from the Payload for Antimatter Matter Explor…
High Energy Positrons From Annihilating Dark Matter
Ilias Cholis, Lisa Goodenough, Dan Hooper +2
Recent preliminary results from the PAMELA experiment indicate the presence of an excess of cosmic ray positrons above 10 GeV. In this letter, we consider possibility that this sig…
High Energy Positrons and the WMAP Haze from Exciting Dark Matter
Ilias Cholis, Lisa Goodenough, Neal Weiner
We consider the signals of positrons and electrons from "exciting" dark matter (XDM) annihilation. Because of the light (m_phi ~< 1 GeV) force carrier phi into which the dark matte…
