Figure 34: The NGC 5291 system [72]. VLA atomic hydrogen 21-cm map (blue) superimposed on an optical image (white). The UV emission observed by GALEX (red) traces dense star-forming concentrations. The most massive of these objects are rotating with the projected spin axis as indicated by dashed arrows. The three most massive ones are denoted as NGC5291N, NGC5291S, and NGC5291W.
