Consistent Radiative Transfer Models including Time Dependent Energy Deposition for Type Ia Supernovae

Many aspects of the explosion mechanism of Type Ia supernovae (SN Ia) still remain unclear -- causing uncertainties in the derived cosmological parameters. Realistic models of the generation and transport of radiation in the ejecta are required which link theoretical explosion models to observations. We aim to construct theoretical spectra and light curves from consistent radiative transfer models that allow to study the dependence of observable features on the physical parameters of the explosion.
