Abstract
We report the discovery towards IRAS 16547-4247 of a chain of H2 2.12 μm emission knots that trace a collimated flow extending over 1.5 pc. IRAS 16547-4247 is a massive young stellar object with a luminosity of 6.2×104 L⊙. It is associated with a thermal radio jet and two non-thermal radio lobes which correspond to the working surfaces of the jet. The geometry of the H2 flow implies that it is driven by the thermal jet. We have also identified an isolated unresolved mid-infrared object associated with the jet and which is likely to be responsible for the excitation of IRAS 16547-4247.
