High-energy neutrinos are detected by the IceCube Observatory in the direction of NGC 1068, the archetypical type II Seyfert galaxy. The neutrino flux, surprisingly, is more than a…
Decomposing the Origin of TeV-PeV Emission from the Galactic Plane: Implications of Multi-messenger Observations
Ke Fang, Kohta Murase
High-energy neutrino and -ray emission has been observed from the Galactic plane, which may come from individual sources and/or diffuse cosmic rays. We evaluate the contribution…
Milky Way as a Neutrino Desert Revealed by IceCube Galactic Plane Observation
Ke Fang, John S. Gallagher, Francis Halzen
The Galactic diffuse emission (GDE) is formed when cosmic rays leave the sources where they were accelerated, diffusively propagate in the Galactic magnetic field, and interact wit…
An optimized search for dark matter in the galactic halo with HAWC
A. Albert, R. Alfaro, C. Alvarez +63
The Galactic Halo is a key target for indirect dark matter detection. The High Altitude Water Cherenkov (HAWC) observatory is a high-energy (~300 GeV to >100 TeV) gamma-ray detecto…
