We have investigated the structures and kinematics of the outflows driven by the YSO DG Tauri, using the Near-infrared Integral Field Spectrograph (NIFS) on Gemini North. The blueshifted outflow shows two distinct components in [Fe II] 1.644 micron emission, which are separated using multi-component line fitting. A stationary recollimation shock is observed, in agreement with prev","authors_text":"(2) Space Telescope Science Institute), Geoffrey V. Bicknell (1), Marc C. White (1), Peter J.
