RGB image, Hα emission map, and broadband images of the central 4″ × 4″ of the six target galaxies. The red circle marks the center of each galaxy. The RGB images in the leftmost column are obtained in the same way as the other ones presented in this paper but using different luminosity cuts to better visualize the bright central regions. The background image in the two rightmost panels is the Hα emission map; the contours show the flux of the broad (light yellow) and narrow (light orange) components of the [O III]5007 line detected with MUSE (Radovich et al. 2019). An interactive visualization of the data presented here is available at https://web.oapd.inaf.it/gullieuszik/hst_gasp_centers and in the online journal.
