The X-shooter slit shown as black lines superposed on the greyscale rendition of the ALMA Band 6 continuum image. The displayed image is [C I] ³P₂−³P₁ emission is only detected in the host galaxy (western component in the greyscale ALMA continuum image), as shown in the moment-zero map plotted as cyan contours (at 0.3, 0.35, 0.4, 0.45, 0.5, and 0.55 Jy beam⁻¹ km s⁻¹). The 18.5 GHz ATCA radio continuum shows a double lobe structure and is overlaid as red contours (at 1, 2, 4, 6, 8, 10, 12, 14, 16 mJy beam⁻¹). [C I] ³P₂−³P₁ emission is not detected in any of the radio lobes. Note that the eastern radio lobe is detected in the ALMA Band 6 continuum image and is interpreted as pure synchrotron emission (Falkendal et al. 2019). The beam size of the ALMA image is shown in the lower left corner.
