Caption

Schematic diagram shows how spheroid formation occurs in distant submillimetre-bright galaxies, and how this process connects to the evolution of giant elliptical galaxies in today's Universe. On the far left, we have RGB images from JWST (using F444W for red, F227W for green, and F150W for blue) showcasing examples from our sample of galaxies. The cyan dashed ellipse marks the concentrated region of submm emission, with zoomed-in views highlighting the ALMA submm images. Also shown is a classification of the galaxies' intrinsic shapes. The average shape parameters for our full sample (green ellipse), a subsample of submm-compact galaxies (orange ellipse), and a subsample of submm-extended galaxies (blue ellipse) are compared to local early-type galaxies (red ellipse) and late-type galaxies (represented by purple and cyan spiral shapes).
