![Fig. 2: Video snapshot of [CII] and CO emission.](http://media.springernature.com/full/springer-static/image/art%3A10.1038%2Fs41550-023-01901-5/MediaObjects/41550_2023_1901_Fig2_HTML.png?as=webp)
The image displays a single velocity channel (16.4 km s−1) of [CII] emission in red (0 to 16 K km s−1) and CO emission in blue (0 to 25 K km s−1), respectively, plotted as square-root values. Areas that are dark in CO (no or little emission) are bright in [CII] and reveal the large spatial extent of [CII] emission. The full video with all velocity channels can be found at https://astro.uni-koeln.de/stutzki/research/feedback/animations.
