[21.05] Indirect Observations of the Dark Matter at TeV Gamma-Ray Energies

J. Hall (Utah High Energy Astrophysics Institute)

Non-baryonic dark matter (DM) could emit gamma rays if the DM consists of weakly interacting massive particles (WIMPs). Particle theories for WIMPs suggest that they could annihilate producing gamma rays as a final product. The Galactic Center dynamics observed in the IR seems to be driven by three million solar masses within 90 AU of the dynamical center of the Milky Way. TeV gamma rays were detected in the same direction. We discuss the possibility that the TeV radiation from the GC results from annihilating WIMPs using a neutralino as our particle model. We use the IR observations to constrain the dark matter density profile. Other DM dominated systems such as dwarf galaxies are also promising for indirect detection of the DM. We discuss an ongoing program to observe DM dominated systems at TeV energies.
