Current cosmological models predict gaseous X-ray halos in star forming spiral edge-on galaxies as a consequence of infalling hot gas from the halo onto the disk. In complete contradiction are models of the ISM, because they attribute the presence of hot halo gas to star forming activity in the disk and assume a large scale transport of matter from the disk into the halo. In order to test the second scenario we propose to use XMM-Newton and observe the X-ray emission of three edge-on galaxies known to possess extended diffuse ionized gas (DIG) and radio continuum halos and search for associated star formation induced hot X-ray halos. This, together with previously obtained multi-wavelength observations would allow us to check the infall vs. the outflow model.
