Faraday rotation and the Galactic B field

 

equation278

equation280

tex2html_wrap_inline3922   The plane of polarisation makes many rotations
tex2html_wrap_inline3922   Measure tex2html_wrap_inline4412 at many different tex2html_wrap_inline4414 , solve for R
tex2html_wrap_inline3922   Unlike extragalactic sources, pulsars show no intrinsic Faraday rotation
tex2html_wrap_inline3922   Observed R = Galactic ISM R
tex2html_wrap_inline3922   tex2html_wrap_inline4428
tex2html_wrap_inline3922   Derive mean field along line of sight
