Dark Matter Searches with HAWC
July 22, 2019
The High Altitude Water Cherenkov Observatory (HAWC) detector has conducted a series of searches for very-high energy gamma-ray signals originating from particle dark matter. HAWC's wide ($\approx$ 2 sr) field of view allows it to search for emission from extended objects such as the M31 galaxy, the Virgo Cluster, and a region of the Galactic Halo. The daily coverage of 2/3 of the sky of HAWC has been used to perform combined analyses of both the dwarf spheroidal and dwarf irregular galaxies. This archival data has also been used for a joint analysis of the dwarf spheroidal galaxies in combination with the Fermi-LAT, HESS, MAGIC and VERITAS experiments. New energy estimation algorithms have also enabled HAWC to search for and constrain gamma-ray line emission from dark matter. We will present the latest results from each of these dark matter analyses, which include some of the strongest limits on dark matter decay.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
