Scientific paper

We present results of high-sensitivity, high-resolution, multi-frequency VLA observations toward the star-forming complex NGC 6334. We find that the H II region NGC 6334E, previously described as spherical, has a shell-like morphology. An additional shell-like radio source, G351.02+0.65, is mapped at 330 MHz. Four radio sources in the NGC 6334 complex present shell-like morphology; their diameters vary from 0.12 pc to 3.5 pc. Compact radio sources are detected at the center of the shells of NGC 6334E and NGC 6334A. These compact sources are believed to be associated with the exciting stars of the H II regions. This is the first time for any H II region that both the shell and the central object are detected simultaneously in the radio.
