Abstract (from CDS):

We present a wideband polarization analysis of the mode-changing pulsar PSR J1938+2213 using the ultra-wideband low-frequency receiver on Murriyang, the Parkes 64 m radio telescope. Polarization profiles for both the burst and weak emission modes are obtained. We find that the pulse widths of the two modes exhibit distinct frequency dependencies: the pulse width increases with frequency in the burst mode, but decreases in the weak mode. The linear and circular polarization fractions also show different trends with frequency between the two modes. Our spectral analysis shows that both modes follow power-law spectra, but with differing spectral indices.
