Left: the continuum-subtracted Hα image of the collisional ring galaxy system. We overplot the 1.36 GHz RACS contours to highlight the cospatiality of the star-forming regions and the radio emission. Right: the W2-band image of the system taken with Swift-UVOT. The overplotted Hα contours (representing the star-forming regions shown in the left panel) reveal that the cospatial bright UV emission likely originated from the massive hot stars. North is up and east to the left.
