The Scale and Strength of the Galactic Magnetic Field According to the Pulsar Data
Abstract
In accordance with the data on the Faraday rotation, angular coordinates, and dispersion measurements and distances of 38 pulsars, the strengthB=2.1±1.1 μG and directionl=99°±24°,b≅0° of the large-scale galactic magnetic field and the mean electron density in the galactic discN e=0.03±0.01 cm-3 are determined. A comparison with the results of a study of the measures of rotation of extragalactic radio sources enabled us to estimate the characteristic half-width of the distribution of the electron density on the Z-coordinate (h≅400 ps). The characteristic size of galactic magnetic field flucturations is shown to be ℒ=100 150 ps.
