Description
We have studied the spatial structure of the three dimensional
large-scale pattern of the Galactic Magnetic Field using the
polarization maps obtained by the WMAP satellite at 22 GHz. By using
different models of the large-scale magnetic field of the Milky Way and
a certain model for the cosmic rays electron distribution, we predict
the expected polarized synchrotron emission. Using a Maximum Likelihood
method, we explore the parameter values which best reproduce the WMAP
data and obtain the marginal probability distribution for each of them.
The model that better reproduces the observed map of polarization is an
axisymmetric model with radial dependence of the strength of the
magnetic field.
