A <i>MeerKAT</i> look at the polarization of 47 Tucanae pulsars: magnetic field implications

ABSTRACT We present the polarization profiles of 22 pulsars in globular cluster 47 Tucanae using observations from MeerKAT radio telescope at UHF band (544–1088 MHz) and report precise values dispersion measure (DM) rotation (RM). use these measurements to investigate presence turbulence electron density magnetic fields. The structure function DM shows a break ∼30 arcsec (∼0.6 pc distance Tucanae) that suggests gas driven by motion wind-shedding stars. On other hand, RM does not show evidence break. This non-detection could be explained either limited number or effects intervening Galaxy along line sight. Future pulsar discoveries help confirm localize turbulence.
