5. Abstract

newcommand\Brute\textttBrute Relying on spherical symmetry when modelling supernova
spectra is clearly at best a good approximation. Recent polarization measurements,
interesting features in flux spectra, and the clumpy textures of supernova remnants
suggest that supernova envelopes are rife with fine structure. To account for this
fine structure and create a complete picture of supernovae, new 3D explosion models
will be forthcoming. To reconcile these models with observed spectra, 3D radiative
transfer will be necessary. We propose a 3D Monte Carlo radiative transfer code,
\Brute, and improvements that will move it toward a fully self-consistent 3D
transfer code. Spectroscopic HST observations of supernovae past, present and future
will definitely benefit. Other 3D transfer problems of interest to HST users like
AGNs will benefit from the techniques developed.
