Using cosmological simulations to make useful, scientifically relevant emission line predictions is a relatively new and rapidly evolving field. However, nebular emission lines have been particularly challenging to model because they are extremely sensitive to the local photoionization balance, which can be driven by a spatially dispersed distribution of stars amidst an inhomogeneous absorbing medium of dust and gas. We explore the virtue of time-dependent radiative transfer modelling as a theoretical tool for unravelling the several unmodeled mysteries in observed emission line patterns that persist in the literature. Coupled with detailed and highly resolved simulations, we also explore questions about the dynamics of early galaxy formation and prepare testable synthetic observations for the next generation of space and ground telescopes.
