Searching for Dark Matter with HAWC

Current cosmological observations indicate that ~27% of the universe is made up of something called dark matter (DM) but no particles in the Standard Model explain its nature. Several beyond Standard Model particles, such as weakly interacting massive particles (WIMP) and axion-like particles (ALPs), have been proposed as DM candidates. These could be detected indirectly by observing the products of their annihilation or decay into Standard Model particles, including gamma rays. Several ground-based and space-based telescopes have led extensive observing campaigns of astrophysical sources that are known to have large concentrations of dark matter to try to understand its particle nature. I will present indirect search results for dark matter from several sources, such as dwarf spheroidal galaxies, the Galactic halo and Virgo cluster, using the High-Altitude Water Cherenkov (HAWC) gamma-ray observatory as well as a combination of results with 4 other gamma-ray telescopes.
