ALMA and HST maps for IRAS 12112+0305. The first and second panels are the CO(2–1) integrated flux and peak intensity for ~10 km s⁻¹ channels, respectively. The contour levels in the second panel correspond to (6, 18, 54, 162, 484) × σ, where σ is the line sensitivity (Table 2). The third panel is the ALMA 248 GHz continuum. The contours in this panel are (3, 27, 81) × σ where σ is the continuum sensitivity (Table 2). The fourth panel shows the near-IR HST/NICMOS F160W map with the CO(2–1) peak contours. The position of the two nuclei is marked with a cross in all the panels. The red hatched ellipse represents the FWHM and PA of the ALMA beam (Table 2).
