Additional stellar components contributing to the overall continuum emission in GalaPy: intrinsic (blue) and attenuated (green) free-free emission from nebular regions, synchrotron emission from SN (red), X-ray emission from high-mass and low-mass binary stars (yellow). For reference, the luminosity from attenuated stellar continuum and dust re-radiation, i.e. the sum of the solid lines in Fig. 11, is also reported (dashed black).
