Research Abstract

We have developed a multi-dimensional radiative transfer code for supernova explosions including polarization, and simulated polarization spectra with various multi-dimensional ion distributions in supernova ejecta. We also performed spectropolarimetric observations of supernovae with Subaru telescope. Adding our new data to the existing datasets, we have constructed the largest data samples of Type Ibc supernovae. By comparing the results of simulations and observations, we showed that a three-dimensional geometry is common in supernovae.
