Left: Hα (image and black contours), CO (blue contours), and 100.5 GHz continuum (dark red contours) emission. Outer contours are at 3σ, with the contours increasing by ﹩\sqrt{2}\sigma ﹩ for Hα and the 100.5 GHz continuum, and by 3σ for the CO(3−2) line. The emission peaks of all lines lies well within the ALMA synthesized beam (bottom left inset). Right: spectra of the CO and Hα emission lines, and a reference absorption line from the DLA (Ni II λ1741); the CO emission and DLA absorption occur at a similar redshift, whereas the Hα emission is slightly offset by ∼220 km s⁻¹. This is similar to the absorber–galaxy pair discussed in Møller et al. (2018), who speculated this could be due to varying absorption across the galaxy. The Gaussian fit to the Hα emission is shown in red.
