Title: Combined Modeling of the Galactic Magnetic Field and Thermal Electrons
Abstract: We report results of a global modelling of the Galactic magnetic field and thermal electron densities, from combined analysis of galactic (pulsar) and extragalactic rotation measures and polarized galactic synchroton emission. We go beyond previous modeling attempts, by using the dispersion measure of galactic pulsars and the emission measure from H_alpha observations by WHAM, to constrain the distribution of thermal electrons, needed to deduce the magnetic field from rotation measures.
