Detection of a new, low-brightness supernova remnant possibly associated with EGRET sources.

COMBI J.A., ROMERO G.E., BENAGLIA P. and JONAS J.L.

Abstract (from CDS):

We report on the discovery of a shell-type supernova remnant in the southern sky. It is a large (∼8°x8°), low-brightness source with a nonthermal radio spectrum, which requires background filtering to isolate it from the diffuse background emission of the Galaxy. Three 3EG γ-ray sources are spatially correlated with the radio structure. We have made 21-cm line observations of the region and found that two of these sources are coincident with HI clouds. We propose that the γ-ray emission is the result of hadronic interactions between high-energy protons locally accelerated at the remnant shock front and atomic nuclei in the ambient clouds.
