Abstract: The number of observed core-collapse supernova lightcurves is growing every day, providing valuable clues about progenitors, stellar evolution, the explosion mechanism, the nuclear equation of state, nucleosynthesis, and the formation of neutron stars and black holes. However, interpreting electromagnetic observables correctly is a formidable challenge, one that requires detailed and accurate theoretical modeling. In this talk, I will present lightcurves and spectra for a suite of core-collapse supernova models, exploded self-consistently in spherical symmetry within the PUSH framework. I will categorize light curves based on morphology and show that the categories relate to the progenitor radius and the mass of the hydrogen envelope. I will also present photospheric and nebular phase spectra that show characteristic iron-line blanketing at short wavelengths. To enable this study, I developed a first-of-its-kind pipeline from a massive progenitor model, through a self-consistent explosion in spherical symmetry, to electromagnetic counterparts. This opens the door to more detailed analyses of the collective properties of these observables.
