Reconstruction of the HostM galaxy in the source plane (delensed) is shown in the left panel, with almost all the details merged into a compact, barely resolved source. Middle panels: galaxy HostM in the F555W-band and the segmentation image with the blue contour at 5σ (left and right, respectively). The three regions 5.1, 5.2, and 5.3 (white apertures with 0.2″ diameter) containing star clusters account for at least 40% of the ultraviolet light of the galaxy. Right panel: same region of the galaxy is outlined with the blue contour in the F275W band probing LyC. It is clear the conspicuous escape of ionizing radiation from the YMC 5.1.
