TeV Observations of the Galactic Plane with HAWC and Joint Analysis of GeV Data from Fermi

Understand

A number of Galactic sources emit GeV-TeV gamma rays that are produced through leptonic and/or hadronic mechanisms.

• Spectral analysis in this energy range is crucial in order to understand the emission mechanisms.
• The HAWC Gamma-Ray Observatory, with a large field of view and location at $19^\circ$ N latitude, is surveying the Galactic Plane from high Galactic longitudes down to near the Galactic Center.
• Data taken with partially-constructed HAWC array in 2013-2014 exhibit TeV gamma-ray emission along the Galactic Plane.
