Abstract Recent results from the CoGeNT Collaboration (as well as the annual modulation reported by DAMA/LIBRA) point toward dark matter with a light (5–10 GeV) mass and a relatively large elastic scattering cross section with nucleons ( σ ∼ 10 − 40 cm 2 ). In order to possess this cross section, the dark matter must communicate with the Standard Model through mediating particles with small masses and/or large couplings. In this Letter, we explore with a model-independent approach the particle… Expand

Observations with the Fermi Large Area Telescope (LAT) indicate an excess in gamma rays originating from the center of our Galaxy. A possible explanation for this excess is the annihilation of DarkExpand
Two Emission Mechanisms in the Fermi Bubbles: A Possible Signal of Annihilating Dark Matter
We study the variation of the spectrum of the Fermi Bubbles with Galactic latitude. Far from the Galactic plane (|b| > 30 degrees), the observed gamma-ray emission is nearly invariant with latitude,Expand
