Search for Gamma-ray Spectral Lines from Dark Matter Annihilation in Dwarf Galaxies with the High-Altitude Water Cherenkov Observatory

The HAWC Collaboration

Local dwarf spheroidal galaxies (dSphs) are nearby dark-matter dominated systems, making them excellent targets for searching for gamma rays from particle dark matter interactions.…

Multiple Galactic Sources with Emission Above 56 TeV Detected by HAWC

HAWC Collaboration, A. U. Abeysekara, A. Albert +99

We present the first catalog of gamma-ray sources emitting above 56 and 100 TeV with data from the High Altitude Water Cherenkov (HAWC) Observatory, a wide field-of-view observator…

Constraints on Spin-Dependent Dark Matter Scattering with Long-Lived Mediators from TeV Observations of the Sun with HAWC

A. Albert, R. Alfaro, C. Alvarez +91

We analyze the Sun as a source for the indirect detection of dark matter through a search for gamma rays from the solar disk. Capture of dark matter by elastic interactions with th…

First HAWC Observations of the Sun Constrain Steady TeV Gamma-Ray Emission

A. Albert, R. Alfaro, C. Alvarez +92

Steady gamma-ray emission up to at least 200 GeV has been detected from the solar disk in the Fermi-LAT data, with the brightest, hardest emission occurring during solar minimum. T…

Search for Dark Matter Gamma-ray Emission from the Andromeda Galaxy with the High-Altitude Water Cherenkov Observatory

A. Albert, R. Alfaro, C. Alvarez +97

The Andromeda Galaxy (M31) is a nearby (780 kpc) galaxy similar to our own Milky Way. Observational evidence suggests that it resides in a large halo of dark matter (DM), mak…
