Zoom on the southwest region of the Veil shell. The first two images show the emission from FUV-heated warm dust and from C⁺. The rightmost image displays a rather different morphology, mostly dominated by extended CO from the molecular cloud behind the shell. Left panel: PACS 70 μm emission at 6″ resolution and positions of the detected CO globules. Middle panel: SOFIA [C II] 158 μm intensity map integrated in the v_LSR = [−7, +20] km s⁻¹ range (Pabst et al. 2019). Right panel: IRAM 30 m ¹²CO (2–1) intensity map in the v_LSR = [−7, +20] km s⁻¹ range. We identified blueshifted CO globules (some of them are labeled) with velocity centroids in the v_LSR range [−7, +6] km s⁻¹ (see Fig. 4).
