TeV gamma-ray sources from a survey of the Galactic plane with Milagro

A survey of Galactic gamma-ray sources at a median energy of similar to 20 TeV has been performed using the Milagro Gamma-Ray Observatory. Eight candidate sources of TeV emission are detected with pretrial significances > 4.5 sigma in the region of Galactic longitude l is an element of [ 30 degrees, 220 degrees] and latitude b is an element of [-10 degrees, 10 degrees]. Four of these sources, including the Crab Nebula and the recently published MGRO J2019 + 37, are observed with significances > 4.5 sigma after accounting for the trials. All four of these sources are also coincident with EGRET sources. Two of the lower significance sources are coincident with EGRET sources, and one of these sources is Geminga. The other two candidates are in the Cygnus region of the Galaxy. Several of the sources appear to be spatially extended. The fluxes of the sources at 20 TeV range from similar to 25% of the Crab flux to nearly as bright as the Crab.
