Abstract: In project C5 of the SFB 676, we simulated the spectra of cosmological Type Ia supernovae in detail. We use state-of-the-art (3D) NLTE spectral synthesis to analyze the observed multi-wavelength spectra of SNe found in the archives, and make predictions for future observations. This helps us to unlock the mystery of the dark energy. For this work, we have extended our general model atmosphere code PHOENIX to simulate SN Ia spectra and light curves. For this we have developed a 3D time-dependent radiative transfer module and a number of additional modules (line opacities, equation of state, non-LTE) to create a PHOENIX/3D packag. This package allows for the same micro-physics as the PHOENIX/1D mode, so that we are in the rather unique position to investigate both 1D and 3D light-curve models with the same micro-physics as main ingredients.
