Studying Galactic Compact Binary Systems with HAWC at Multi-TeV Energies

Compact binary systems can emit very high energy gamma rays via particle acceleration and interactions within jets and accretion disks. Measurements of these objects can help explain mechanisms of cosmic-ray acceleration and propagation, which are not fully understood. The High Altitude Water Cherenkov (HAWC) Observatory is a wide field-of-view and high-uptime detector of TeV gamma rays that is capable of long-term measurements of transient and periodic sources such as compact binaries. We report on observations of several Galactic binaries with HAWC, and discuss ongoing multi-wavelength campaigns as well as modeling of gamma-ray backgrounds in the Northern Hemisphere.
