Gaseous halos of spiral galaxies: Ralf-Juergen Dettmar Colloquium

Using multi-wavelengths observations of edge-on galaxies a
correlation of the properties of gaseous halos with the
star formation in the underlying disk is established for
late type galaxies. This can be understood in the
framework of the so-called "disk-halo interaction"
scenario and the results are discussed in the context of
global models for the interstellar medium. Special
attention is given to the role of magnetic fields as
studied through radio continuum polarization observations.
