Contours of ¹²CO(1–0) (12-m) overlaid on HST F555W images (left panels), and MUSE E(B − V) maps (right). The ¹²CO(1–0) contour levels correspond to (0.01, 0.025, 0.05, 0.1, 0.2, 0.3, 0.4, 0.450, 0.750) Jy km s⁻¹ beam⁻¹ for NGC 625; (0.01, 0.025, 0.05, 0.1, 0.2, 0.3) Jy km s⁻¹ beam⁻¹ for NGC 1705; (0.01, 0.025, 0.05, 0.1, 0.15, 0.25, 0.4, 0.5, 0.75, 1.0, 1.5) Jy km s⁻¹ beam⁻¹ for NGC 5253. Also marked A–D in the left panels are the HII regions identified with radio continuum maps of NGC 625 by Cannon et al. (2004); the dust clouds and SSC in NGC 1705 identified from Spitzer observations (Cannon et al. 2006); and the unusual CO+dust cloud “D1” in NGC 5253 that coincides with the brightest, highly dust embedded SSC (Turner et al. 2017). The ALMA 12-m beam is shown in the lower-left corner of the left panels.
