Moment-0 maps for all galaxies in our sample divided into regular (on the left) and irregular (on the right), depending on whether the fraction f of spaxels with H I column density below 10²⁰ cm⁻² is higher or lower than 0.65 (see Fig. 8). f values of individual galaxies are annotated in each panel. The red dots mark TNG50 galaxies that have AGN feedback in thermal mode. The black iso-contours from the HR maps are drawn at levels of 10¹⁹, 10²⁰ (thicker line), 10^20.5, and 10²¹ cm⁻². An additional iso-contour from the LR maps at 10¹⁸ cm⁻² is shown in blue. The green boxes highlight galaxies observed with MeerKAT. The maps were derived with SoFia-2, using the same parameters for all galaxies.
