Integrated spectral energy distribution of one representative NEWCLUSTER galaxy as produced by the SKIRT radiative transfer simulations assuming a DTM ratio of 16%. Left: Full SED in the observed frame, shown for the face-on (black) and edge-on (teal) configurations, spanning wavelengths from the ultraviolet to the millimeter. The shaded vertical regions show the coverage of ALMA bands 3, 7, and 9, and the dashed line demonstrates the JWST IFU range. Right: Examples of continuum-subtracted emission lines extracted from the same SED.
