Multi-wavelength morphology of the H1429−0028 system. Images are 4′′ in size. North is up; east is left. Both the foreground galaxy and the lensed galaxy − in the form of an Einstein-ring − are detected and resolved in the near-IR high-resolution imaging (top-row; F110W, H, and K_s are displayed with an asinh scale, but with different flux ranges). The knot nomenclature adopted throughout the paper is indicated in the K_s imaging. Top-right panel shows a near-IR colour image (displayed with a sqrt scale; images combined with the same flux range). Two bottom-left panels show ALMA 234- and JVLA 7-GHz continuum maps (restored with uniform and Briggs robust = 0.5 weightings, respectively). These are compared against F110W and K_s morphologies in the two bottom-right panels. Blue contours (at 3σ, -increments up to 675 μJy beam^-1, 15σ, and 25σ, with σ = 78 μJy beam^-1) refer to the 234 GHz continuum, while red contours (at 3σ, -increments up to 72 μJy beam^-1, 15σ, and 30σ, with σ = 10 μJy beam^-1) refer to the 7 GHz continuum.
