Morphology of the M83 starburst region. The background image shows a zoom-in into the three colour stellar composite from MUSE (Fig. 2). The purple dashed lines indicate the schematic location of the outer circumnuclear ring and dust inner bar from Elmegreen et al. (1998). The brightest region of star formation (‘starburst arc’) is visible inside the ring. Black lines indicate the location of the kinematic features discussed in Sect. 6. The scalebar of 20″ corresponds to ≃500 pc at the distance of our target.
