Abstract
Photoionization by stars cannot be the only cause for the diffuse ionized gas component in the distant halos of galaxies. Quasistationary localized magnetic reconnection can efficiently contribute to the ionization of the extraplanar halo gas. The gas is heated and re-ionized in numerous current filaments fast enough to compensate recombination. The necessary magnetic energy is provided by the disk activity.
