Analysis of molecular gas dynamics in NGC 4593. Top: Red-circled region (a) indicates potential non-circular motion due to the outflow of cold molecular gas, visible on the mean velocity map (background). The central dashed circle (region b) highlights the CMZ-like ring, which contains significant molecular gas. Bottom: Comparison between the CO(2−1) ALMA observations (green) and the 3D-BAROLO model (blue) for NGC 4593. The plot shows the average flux as a function of velocity, with residuals (orange) and possible outflowing gas from region (a) highlighted in red.
