摘要：
We present radio observations of the black hole candidate X-ray binary GX 339-4 with the Australia Telescope Compact Array. Mapping of the highest resolution 3.5-cm data reveals a jet-like extension, which if confirmed would be the first detection of a radio jet from a persistent black hole candidate system. No evidence is found for associated structures such as bowshocks or jet lobes on larger scales. The spectral energy distribution from 22 to 3 cm is relatively flat, suggesting that emission is dominated by a compact absorbed core.
