Spatial distribution of the blue- and redshifted [C II] high-velocity gas in RCW 79. Top: Intensity map, integrated over the blueshifted high-velocity wing (i.e., −70 to −52.6 km s⁻¹). The high-velocity gas is also observed to the south of RCW 79. The white contours indicate the total integrated [C II] emission (presented in Fig. 1) starting at 50 K km s⁻¹ with increments of 50 K km s⁻¹. Bottom: Same, but for the redshifted high-velocity wing (i.e., −41.4 to −25 km s⁻¹). The high-velocity gas is observed passing through the openings of the H II region in the northeast and northwest.
