Cutouts of JWST images (as different surveys use different filters, the filter in which the companion is most clearly present is shown: F182M for GSDY and z7-GSD-3811, F200W for EGSY8p68, F115W for CEERS-1027, JADES-GS-z7-LA and COSY and F150W for JADES-GS+53.15682-27.7671 and z7-13433) showing the components of each system. All images are smoothed with a Gaussian of FWHM ≈ 0.7 kpc to enhance the visibility of the companion, except for EGSY8p68, where the three components become unresolved if we smooth the images. We include the unsmoothed images as subpanels in the top right of each panel to emphasize that the companion is always visible before smoothing. We use different color-bar ranges for each system to make the companion galaxy well defined, so some unsmoothed images have what seems like a nosier background than others. Orange arrow, position of the main target (*A in the text); blue arrow, position of the first companion (*B); green arrow, position of the third companion, if any. The name of each candidate is indicated in the bottom-right corner. Scale bars, 0.5″.
