Synthetic emission at different wavelengths from a 3D r-MHD simulation. For context, panels a and f show the Hα line wing (−1.5 Å) and integrated Si IV 1393 Å intensity, respectively. The emission at the simulation’s original scale (0.065″ px⁻¹) in AIA 94, 171, 304 Å, and ALMA 3 mm is shown in panels b–e, respectively, and at the spatial resolution of the observations (0.3″ px⁻¹) in panels g–j, correspondingly. The arrows indicate the locations of one EB and one UVB as labeled in the leftmost panels. Panels b–d and g–i: are displayed in logarithmic scale; panels e, f, j: are shown in power-law scale. The dotted lines in the upper-right panel indicate the locations of the slices shown in Fig. 11.
