Abstract
We present high angular resolution (12''-24'') and high-sensitivity 12CO and 13CO J = 2-1 and J = 1-0 observations of the HH 1-2 outflow. The observations show the molecular counterpart, moving with a velocity of 30 km s-1, of the optical bipolar system driven by the VLA 1 embedded source. Along with the optical jet there are certain regions where the molecular gas reaches deprojected velocities of 100-200 km s-1 and that we interpret as the molecular jet. The bipolar CO outflow has a length of ~260'' with a curved morphology toward the north where it extends beyond the HH 1 object (120''). Two new molecular outflows have been detected, one arising from IRAS 05339-0647, which excites the HH 147 optical flow, and another powered by VLA 2, which drives the HH 144 optical outflow. The molecular outflow driven by the VLA 3 source is also clearly detected and spatially resolved from the VLA 1 main outflow.
