An attempt to identify the extended synchrotron structure associated with the micro-quasar GRS 1915+105

The energy ejected from the galaxy micro-quasar GRS 1915+105 in the form of jets is expected to lead to formation of an extended double lobe/hot-spot structure with an energy content comparable to an average supernova remnant . We used the Effelsberg 100 m telescope at 10.45 GHz in attempt to identif y such structures. For this distant galactic plane source, no definite iden tification was possible. due to high confusion by numerous background sourc es; however, a few suspect structures were identified.
