Adaptive Optics Reveals Strange Dynamics in Ultra-Compact Star-forming Region

Velocity (km s−1) for the principal component of the Brγ line in each NIFS spaxel derived from the data with a Gaussian fit to the line profile. The mean Brγ velocity (VLSR = −62.5 km s−1) of the principal component has been removed from the map. The bipolar structure does not line up with any known point source, and the axis does not align with the direction of the large scale ionized flow detected at radio wavelengths. The peak relative velocities are −24 km s−1 and +31 km s−1, but the color map is “stretched” slightly to show smaller velocities.
