Dispersion measure variations in a sample of 168 pulsars

We analyse dispersion measure (DM) variations in six years of radio observations of more than 160 young pulsars, all gamma-ray candidates for the Fermi gamma-ray telescope mostly located close to the Galactic plane. DMs were fitted across 256 MHz of bandwidth for observations centred at 1.4 GHz and...
