Abstract: | A method is introduced for constructing two-color maps for the in-plane component of the magnetic field of our galaxy in (R,
l) and (DM, l) coordinates. It is shown that, in agreement with the standard models of the galactic magnetic field, the magnetic
field in neighboring spiral arms reverses direction. However, the magnetic field in the spiral arm of Sagittarius differs
significantly from the standard magnetic field model, with the major difference being that the magnetic fields in the southern
and northern hemispheres are oppositely directed in the spiral arm of Sagittarius. It is proposed that this distribution of
the magnetic field can be explained best by assuming that the spiral arm of Sagittarius, or, at least, a magnetic spiral arm
in that region, is not symmetric with respect to the galactic plane and lies mainly in the northern hemisphere. |
