Scientific paper

We propose 65 ksec ACIS-S observations of the edge-on disk galaxies NGC 5775 and NGC 3044, both of which show bright, extraplanar ionized gas in H alpha and have extensive radio continuum halos. The primary goal is to image the diffuse soft X-ray emission expected (and already observed with ROSAT in the case of NGC 5775) to result from injection of energy and momentum into the halo by stellar winds and supernovae. The physical parameters (e.g. luminosity, mass, scaleheight, density and temperature) of X-ray emitting gas will be derived. The X-ray data will be compared with existing optical and radio data to constrain the physics of disk-halo interactions in these galaxies.
