Integrated intensity map and kinematic structure of RCW 79 in [C II]. Top left: [C II] integrated intensity map of RCW 79 between −70 and −20 km s⁻¹ with the integrated ¹²CO(3–2) emission at 25, 50, 75, and 100 K km s⁻¹ overlaid by white contours. The white plus signs and black crosses respectively give the locations of the previously identified O stars and YSOs in the region. The red arrows outline the cuts used for the PV diagrams below, with the arrow indicating a positive radius. The cyan circle delimits the region used for the average spectrum presented in Fig. 2 and the magenta circle indicates the compact H II region. Movies of PV cuts over the map are found online and at https://hera.ph1.uni-koeln.de/~nschneid/rcw79_animations.html. Top right: 2D projection of an interactive 3D isocontour plot, which is found at the same url as above. Bottom left and right: [C II] PV diagrams with the ¹²CO(3–2) emission indicated by white contours. Both blue- and redshifted high-velocity [C II] emission is detected. The high-velocity [C II] gas is typically found toward the edges of the H II region, and flowing out through the opening in the northwest (see PV cut 2).
