A search for radio counterparts of southern unidentified EGRET sources.

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

Abstract (from CDS):

We present results of 1.42 GHz continuum and H I line observations of the environs of the unidentified EGRET sources 3EG J0724-4713 and 3EG J0725-5140. Using a filtering technique, we have eliminated from the radio continuum images the background diffuse radiation that originates in the Galactic disk. This enables us to study the presence of weak radio sources within the likelihood contours of the γ-ray detections. The H I line observations provide additional information about the structure of the interstellar medium in the line of sight to the sources, which is relevant in case of a Galactic origin. We discuss the nature of the individual sources in the light of the results.
