Measurements of the Circular Polarization of Radio Sources at 1.4 and 5 GHz

Abstract

Recently reported measurements of the circular polarization of the radiation from extragalactic radio sources have indicated that the polarization may be variable1 and that the polarization is greatest for sources with flat or inverted spectra2,3. To confirm these findings and to clarify the relationship between observation and theory4−6 we have initiated a series of measurements using the Parkes 64-m telescope.
