Scientific paper

We present VLA observations of the (1, 1) inversion transition of ammonia toward four regions with high-velocity gaseous outflow: HH 26-IR, GGD 12-15, Serpens, and V645 Cygni. We detected small-scale structure ( ˜10") in all sources. In HH 26-IR and GGD 12-15 we find double-maximum structures that could be related to the collimation processes of the outflow. The condensations observed in Serpens and V645 Cygni appear to be the cores of the more extended structures mapped with a single dish.
