The box shows the field observed with Gemini-NIRI and displays the broad Ks-band emission. The blue contours are the blueshifted CO outflow found by Ortega et al. (2012) and the black ones represent the 4.5 μm IRAC emission that delimits the EGO G45.47+0.05 boundaries. The angular resolution of the CO emission is about 20′′. The blue arrow shows the alignment between the structure that connects the IR source with the near-IR arc-like features and the blueshifted CO outflow.
