H I spatial distribution compared to X-ray, CO, Hα and optical maps. The H I contours are at drawn at column densities of N_HI = 2.3, 4.6, 9.2, 18.4 × 10¹⁹ atoms/cm². The orange contour is the galaxy disc, as in Fig. 1. Top left panel: H I over Chandra 0.6–2.0 keV count X-ray image. Top right panel: H I overlaid on the CO (2–1) flux intensity map from ALMA. Bottom left and right panels: H I contours over the Hα emission from MUSE and the HST WFC3 image (see also Fig. 1 in Waldron et al. 2023), respectively.
