Extended Data Fig. 4: Line and continuum ALMA images of the field around J 012555.11−012925.00.
From: Quasar radiation transforms the gas in a merging companion galaxy

a, b, c, The integrated emission of CO(3-2) and C I(2-1) lines, together with CO(7-6)/(3-2) line ratios, respectively, centered on the companion galaxy. d, e, ALMA band 6 and 3 wideband continuum images, respectively. The gray contours indicate the CO(7-6) emission shown in Fig. 1. The green hatch ellipses in each panel represent the synthesized beam.
