Abstract: We are undertaking a project to model radio continuum and polarization emission from supernova remnants (SNRs). We will make use of the International Galactic Plane Survey data and the new GALFACTS survey, which provide fully-sampled radio polarization data at 1420 MHz. We will construct physically-consistent models of extended polarized emission and depolarization effects on the background, and observe these models with a simulated radio telescope beam to produce synthetic Stokes Q & U data. These will be compared to observations to constrain the line-of-sight magnetic field in selected Galactic SNRs. Using X-ray data, we will disentangle the thermal and non-thermal X-ray emission which will provide additional constraints on the modeled electron density and magnetic field. We are starting with analysis of the SNR S147, which shows some interesting depolarization in the shell in addition to a polarized region that is coincident with the pulsar detected in X-rays. We present a preliminary model as well as an investigation of the polarized feature that may be a detection of the pulsar wind nebula.
