Appendix A: Image gallery

thumbnail Fig. A.1

Top: grayscale of the 8 μm GLIMPSE image of GMF 18.0-16.8. The white contour shows the 13CO integrated intensity of 2 and 7 K km s-1. IRAS sources and W 37 are marked with blue stars, and Hii regions found in the CORNISH survey are shown in blue circles. M 16 is a prominent emission source in this region, north of the filament but at a consistent characteristic velocity. Bottom: color scale of the centroid velocity field from the GRS 13CO data where the integrated intensity is above 1 K km s-1 in the indicated velocity range, shown in the color bar in km s-1. The blue contour is ATLASGAL 870 μm emission of 250 mJy beam-1. In magenta circles, we show all vlsr measurements of BGPS clumps that have velocities within the 13CO velocity range and with × those vlsr values outside of the 13CO velocity range. The magenta diamonds are positions in the Wienen et al. (2012) catalog with a matching velocity. The black contours are the 13CO integrated intensity at 2 and 7 K km s-1.

Top: grayscale of the 8 μm GLIMPSE image of GMF 20.0-17.9. The white contour shows the 13CO integrated intensity of 3.5 K km s-1. IRAS 18248-1229 and W 39 are both labeled with blue stars, and Hii regions from the CORNISH survey are marked with blue circles. The black line is the location of the Galactic plane at the distance of this filament. Bottom: color scale of the centroid velocity field from the GRS 13CO data where the integrated intensity is above 1 K km s-1 in the indicated velocity range, shown in the color bar in km s-1. The blue contour is ATLASGAL 870 μm emission of 250 mJy beam-1. In magenta circles, we show all vlsr measurements of BGPS clumps that have velocities within the 13CO velocity range and with × those vlsr values outside of the 13CO velocity range. The diamonds are positions in the Wienen et al. (2012) catalog with a matching velocity. The black contour is the 13CO integrated intensity at 3.5 K km s-1.

Top: grayscale of the 8 μm GLIMPSE image of GMF 26.7-25.4. The white contour shows the 13CO integrated intensity of 2 K km s-1. The blue star is the position of IRAS 18348-0526, and the blue circles are CORNISH detected Hii regions. Bottom: color scale of the centroid velocity field from the GRS 13CO data where the integrated intensity is above 1 K km s-1 in the indicated velocity range, shown in the color bar in km s-1. The blue contour is ATLASGAL 870 μm emission of 250 mJy beam-1. The magenta diamond indicates a pointing from the Wienen et al. (2012) NH3 catalog that has a consistent velocity, though the other two pointings (×, in the bottom right corner) have velocities outside of the 13CO range. The black contour is the 13CO integrated intensity at 2 K km s-1.

center: grayscale of the 8 μm GLIMPSE image of GMF 38.1-32.4. The white contour shows the 13CO integrated intensity of 0.5 K km s-1 between 50 and 60 km s-1 (left), and the yellow contour shows the 13CO integrated intensity of 0.5 K km s-1 between 43 and 46 km s-1 (right). Blue stars indicate the positions of IRAS sources and W 44, and blue circles are the positions of Hii regions from the CORNISH survey. The solid black line is the location of the Galactic plane at the distance of the 5060 km s-1 filament, and the dashed black line corresponds to the plane at the distance of the 4346 km s-1. Right and left: color scale of the centroid velocity field from the GRS 13CO data for the 43 to 46 km s-1 (right) and 50 to 60 km s-1 (left) filaments where the integrated intensity is above 1 K km s-1 in the indicated velocity range, shown in the color bar in km s-1. The blue contour is ATLASGAL 870 μm emission of 250 mJy beam-1 within each masked region. In magenta circles, we show all vlsr measurements of BGPS clumps that have velocities within the respective 13CO velocity ranges and with × those vlsr values outside of the 13CO velocity ranges. The diamonds are positions in the Wienen et al. (2012) catalog with a matching velocity. The black contours are the 13CO integrated intensity of 2 and 7 K km s-1.
