ALMA images of the dust continuum and molecular gas emission in G09v1.97. Upper row – from left to right: 1.94 mm (rest-frame ∼419 μm) dust continuum image with resolution, with contours starting from ±4σ in steps of ±6σ (σ = 0.03 mJy beam⁻¹); 0.87 mm (rest-frame ∼188 μm) dust continuum image with resolution, with contours starting from ±4σ in steps of ±6σ (σ = 0.23 mJy beam⁻¹); the 1.94 mm dust continuum contours overlaid on the Keck-II Ks-band image, which shows the two deflecting foreground galaxies at z = 0.626 (G1) and z = 1.002 (G2). Lower row – from left to right: velocity-integrated molecular line emission images with resolution in: CO(6–5) with contours from ±4σ in steps of ±4σ; H₂O(2₁₁−2₀₂) with contours from ±4σ in steps of ±3σ; and H₂O⁺ with contours from ±3σ in steps ±1σ. The σ values for the CO, H₂O, and H₂O⁺ images are 0.05, 0.06, and 0.05 Jy km s⁻¹ beam⁻¹, respectively. The synthesized beam sizes are displayed in the lower left corners of each panel. The images show an almost complete Einstein ring, to first order, with similar spatial distributions for the dust continuum, CO and H₂O line emission.
