Investigating IceCube Neutrino Alerts with the HAWC Gamma-Ray Observatory

Neutrino emission from astrophysical sources has long been considered a signature of cosmic-ray acceleration. The IceCube Neutrino Observatory has observed a diffuse flux of TeV–PeV neutrinos, but very few confirmed sources have emerged. With the recent publication of the IceCube Event Catalog (IceCat-1), IceCube has r...

Evidence of a spectral steepening of the gamma-ray emission from the Galactic center ridge

Very high-energy (VHE) γ-ray emission detected from the central molecular zone (CMZ) hints at diffusive propagation of cosmic rays (CRs) injected continuously near the Galactic center (GC). Using H.E.S.S. VHE γ-ray observations, we aim to construct a multicomponent description of the region in order to derive the spati...
