Comparison between the ALPINE and CRISTAL [C II] observations of the CRISTAL-05 galaxy at z = 5.5 (Posses et al. 2025). Top: [C II] integrated intensity map based on the ALPINE Natural weighting observations (left), and the CRISTAL higher-angular observations using the Natural (without applying a uv-taper; center) and Briggs (right) weighting. Bottom: Similar to the top panels, but this time showing the [C II] velocity field.
