OBSERVATIONS OF THE RADIO-EMISSION FIELD AROUND THE GAMMA-RAY SOURCE 2EG J1834-2138

We present results of a study of the radio emission field around the b est estimate position of the low-latitude EGRET source 2EG J1834 - 213 8. The identification of this gamma-ray source with the gravitational lensed AGN PKS 1830 - 211 has been recently proposed by Matter et al. (1997). Additional support for this identification is provided here. C ontamination produced by the diffuse disk emission has been removed fr om new radio images of the surrounding region of 2EG J1834 - 2138 allo wing a determination of the fine radio structure. Several previously u nnoticed supernova remnants have been found within a few degrees from the gamma-ray source. However, the only strong radio source within the 95% source location confidence contour of 2EG J1834 - 2138 is PKS 183 0 - 211. In addition, both spectrum and variability analysis of the EG RET data support the identification of both sources.
