Velocity-integrated CO(12–11) line emission from the central region of W2246–0526 (host), the extended dust continuum emission at rest-frame 155 μm from Fernández Aranda et al. (2025) (pink contours), and the VLA B and D configuration CO(2–1) emission (cyan contours). The physical scale is shown in the lower right corner, with the corresponding synthesised beams (pink: dust continuum; cyan: CO(2–1); gold: CO(12–11)). The dash-dotted white circle indicates the r = 0.6″aperture used to extract the flux density measurements of the host; i.e. not including any of the extended emission. Contours reflect [4,5,6,...] × r.m.s) for CO(2–1), and [3, 2^(n/2)] × r.m.s. (with n = 4,5,6,...) for the continuum.
