We present high spatial resolution mapping (HPBW=32") of outflow regions in NGC 1333 and NGC 7129 in the J=1-0 CO and 13CO lines. The blueshifted outflow related to the Herbig Haro objects HH 7–11 has been found to be clumpy and closely associated with the visible HH emission. The CO flow stops abruptly at HH 7, the outmost HH object of the group, as seen from the suspected excitation source, the low luminosity star SSV 13, also an H2O maser. Although the flow is bipolar, the blue- and redshifted flows are not exactly aligned but inclined relative to each other at an angle ~7°. We suggest that the redshifted flow is expanding through much denser gas, and that the flow is deflected by the surrounding dense cloud. South of HH 7–11, near the masers C and D, we have also found another outflow region, which we have not yet mapped in detail.

In the NGC 7129 region there are two distinct high velocity outflows, both of which appear to have their activity centers associated with H2O masers and FIR sources. In the northern outflow, which probably is driven by the Herbig Be star Lkhα 234, most of the high velocity gas is observed to be redshifted , with very little gas in the opposite direction. The spatial distribution of 13CO close to LkHα 234 indicates strong density variations, which we interpret as a rotating gaseous disk, responsible for the collimation of the flow. The second outflow, associated with an deeply embedded star, has more symmetric wings.
