The current generation of gamma-ray instruments have produced a treasure trove of astrophysical discoveries. Among them are a new class of objects tentatively designated high-mass gamma-ray binaries (HMGBs). Thought to be systems containing the colliding wind of a massive star and a young pulsar, these objects are distinguished by emission >1 MeV dominating their spectral energy distributions. We present a multiwavelength study of a newly detected gamma-ray source, HESS J1844-030, utilizing Chandra, Fermi, and VERITAS to show that its spatial, spectral, and flux variability properties are compatible with a classification as a HMGB. The current generation of instruments have identified …
