Fig. 2
90 cm emission (blue contours) superimposed on the Spitzer-IRAC 8 μm emission (grayscale). The pink dashed circles represent bubbles N19 and RCW165. The contour levels start from 0.021 Jy beam−1 (3σ) in steps of 3σ. The pink dashed lines indicate the dark IR clouds (Peretto & Fuller 2009), while the red arrows show two gas flows. The pink stars mark the positions of the two ionizing stars of N19 (Evans et al. 2005).
