Event Details

There is overwhelming evidence that non-baryonic dark matter constitutes ~27% of the energy density of the Universe. Many promising dark matter candidates, like Weakly Interacting Massive Particles (WIMPs) are expected to produce gamma rays via annihilation or decay in the Universe. These gamma rays would be detected by spacebased detectors like the Fermi Large Area Telescope (LAT) or by ground-based instruments like the High Altitude Water Cherenkov (HAWC) Observatory. A detection of gamma rays from dark matter would not only confirm its existence through a non-gravitational force, but also indicate physics beyond the Standard Model. Together with the LAT and ground-based observatories like HAWC, we can probe dark matter masses from ~1 GeV to 100 TeV I will present results from recent searches for gamma-ray excesses in areas of large dark matter concentration, like the Galactic center and dwarf spheroidal galaxies, from both the LAT and HAWC Collaborations.
