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.…

Constraints on Lorentz invariance violation from HAWC observations of gamma rays above 100 TeV

HAWC Collaboration, A. Albert, R. Alfaro +90

Due to the high energies and long distances to the sources, astrophysical observations provide a unique opportunity to test possible signatures of Lorentz invariance violation (LIV…

Combined Dark Matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, HESS, MAGIC and VERITAS

Louise Oakes, Celine Armand, Eric Charles +13

The search for Dark Matter (DM) has great potential to reveal physics beyond the Standard Model. As such, searches for evidence of DM particles are being carried out using a wide r…

Searching for Dark Matter in the Galactic Halo with a Wide Field of View TeV Gamma-ray Observatory in the Southern Hemisphere

Aion Viana, Harm Schoorlemmer, Andrea Albert +3

Despite mounting evidence that dark matter (DM) exists in the Universe, its fundamental nature remains unknown. We present sensitivity estimates to detect DM particles with a futur…

Pulsars in a Bubble? Following Electron Diffusion in the Galaxy with TeV Gamma Rays

H. Fleischhack, A. Albert, C. Alvarez +32

TeV Halos, extended regions of TeV gamma-ray emission around middle-aged pulsars, have recently been established as a new source class in gamma-ray astronomy. These halos have been…

Looking Under a Better Lamppost: MeV-scale Dark Matter Candidates

Regina Caputo, Tim Linden, John Tomsick +6

The era of precision cosmology has revealed that about 85% of the matter in the universe is dark matter. Two well-motivated candidates are weakly interacting massive particles (WIM…
