The H.E.S.S. Collaboration has reported a high-energy spherically symmetric diffuse γ-ray emission in the inner 50 pc of the Milky Way, up to ∼50 TeV. Here, we propose a leptonic model which provides an alternative to the hadronic scenario presented...

Ruling out the light weakly interacting massive particle explanation of the Galactic 511 keV line (2016)
Journal Article
Wilkinson, R., Vincent, A., Boehm, C., & McCabe, C. (2016). Ruling out the light weakly interacting massive particle explanation of the Galactic 511 keV line. Physical Review D, 94(10), Article 103525. https://doi.org/10.1103/physrevd.94.103525

Over the past few decades, an anomalous 511 keV gamma-ray line has been observed from the center of the Milky Way. Dark matter (DM) in the form of light (≲10  MeV) weakly interacting massive particles (WIMPs) annihilating into electron-positron pairs...

Isotropic extragalactic flux from dark matter annihilations: lessons from interacting dark matter scenarios (2016)
Journal Article

Journal of Cosmology and Astroparticle Physics, 2016(08), Article 069. https://doi.org/10.1088/1475-7516/2016/08/069

The extragalactic γ-ray and neutrino emission may have a contribution from dark matter (DM) annihilations. In the case of discrepancies between observations and standard predictions, one could infer the DM pair annihilation cross section into cosmic...

The Spatial Morphology of the Secondary Emission in the Galactic Center Gamma-Ray Excess (2016)
Journal Article
Lacroix, T., Macias, O., Gordon, C., Panci, P., Boehm, C., & Silk, J. (2016). The Spatial Morphology of the Secondary Emission in the Galactic Center Gamma-Ray Excess. Physical Review D, 93(10), Article 103004. https://doi.org/10.1103/physrevd.93.103004

Excess GeV gamma rays from the Galactic Center (GC) have been measured with the Fermi Large Area Telescope (LAT). The presence of the GC excess (GCE) appears to be robust with respect to changes in the diffuse galactic background modeling. The three...

Physics from solar neutrinos in dark matter direct detection experiments (2016)
Journal Article
Cerdeño, D. G., Fairbairn, M., Jubb, T., Machado, P., Vincent, A., & Boehm, C. (2016). Physics from solar neutrinos in dark matter direct detection experiments. Journal of High Energy Physics, 2016(5), Article 118. https://doi.org/10.1007/jhep05%282016%29118

The next generation of dark matter direct detection experiments will be sensitive to both coherent neutrino-nucleus and neutrino-electron scattering. This will enable them to explore aspects of solar physics, perform the lowest energy measurement of... Read More about Physics from solar neutrinos in dark matter direct detection experiments.

Radiative Model of Neutrino Mass with Neutrino Interacting MeV Dark Matter (2016)
Journal Article

We consider the radiative generation of neutrino mass through the interactions of neutrinos with MeV dark matter. We construct a realistic renormalizable model with one scalar doublet (in additional to the standard model doublet) and one complex sing...
