Caption: Figure 1.

Composite RGB images of galaxies in our sample. Hα, continuum-subtracted Lyα, and FUV are shown by red, green, and blue, respectively. Contours represent 0.3–10 keV X-ray surface brightness with the significance for each object (in units of σ, where σ is measured from a local background annulus) and Gaussian smoothing kernel in parentheses: Haro 11: 1.7, 15, 28, 42, and 75σ (no smoothing); ESO 338-IG004: 2.0, 6.0, and 11σ (2 pixels); IRAS 08339+6517: 5.9 and 14σ (2 pixels); NGC 6090: 3.9, 5.1, and 5.9σ (2 pixels); LARS 01: 4.0, 6.0, and 8.0σ (3 pixels); LARS 03: 2.8, 4.1, 4.9, and 6.3σ (3 pixels).
