12″ × 12″ cutouts of the four most CO-luminous SQuIGG﹩\overrightarrow{L}﹩E galaxies in the new sample. For each galaxy, we show the HSC i-band image, the 2 mm continuum image (collapsing the three ALMA spectral windows that were not centered on CO(2–1)), the CO(2–1) Moment 0 image, the CO(2–1) Moment 1 image, and the collapsed CO(2–1) spectrum within a 2″ aperture (also indicated as a red circle). In all ALMA images, the synthesized beam is shown as a gray circle, and contours of 2σ, 4σ, 6σ, and 8σ are shown as increasingly thick lines. The velocity region integrated to measure the CO flux is shown with dashed lines.
