The Distribution of Linear Polarization over 13 Extended Sources at 21·2 cm Wavelength

Abstract

The distribution of linear polarization over 13 bright radio sources has been determined at 21 cm wavelength with an east-west interferometer. The results are presented in the form of strip brightness distributioIlJ3 of polarized flux and direction of polarization, with a resolution of l' by 20'. It is suggested that axial rotation during evolution contributes to the observed polarization features of extended radio sources.
