28 X-rays from the disk-halo interface in spirals Ralf-Jürgen Dettmar @X-rays from Nearby Galaxies ESAC 6.9.2007 28 Summary: gas halo ISM is „multiphase“ the presence of ionized gas and CRs in halos is correlated with the star formation in the underlying disk observed „X-ray hot halos“ fit into this general picture (temp. gradients) a strong poloidal component of the magnetic field is associated with the presence of gaseous halos the warm ionized gaseous halos rotate differentially showing decreasing rotation with increasing hight above the plane
