Abstract

Description

We present high-resolution 1.4 GHz Australia Telescope Compact Array polarimetric observations of Vela X, the pulsar wind nebula of the Vela SNR. We find that the linearly polarized emission is only partially correlated with total intensity. There are many depolarization features, some of which are coincident with foreground H-alpha filaments. Further study of these should provide measurements of the magnetic field in the remnant's shell.
