High-frequency observations of southern pulsars.

JOHNSTON S., KARASTERGIOU A. and WILLETT K.

Abstract (from CDS):

We present polarization data for 32 mainly southern pulsars at 8.4 GHz. The observations show that the polarization fraction is low in most pulsars at this frequency except for the young, energetic pulsars which continue to show polarization fractions in excess of 60 per cent. All the pulsars in the sample show evidence for conal emission with only one-third also showing core emission. Many profiles are asymmetric, with either the leading or the trailing part of the cone not detectable. Somewhat surprisingly, the asymmetric profiles tend to be more polarized than the symmetrical profiles. Little or no pulse narrowing is seen between 1 and 8.4 GHz. The spectral behaviour of the orthogonal polarization modes and radius to frequency mapping can likely account for much of the observational phenomenology. Highly polarized components may originate from higher in the magnetosphere than unpolarized components.
