Disk-halo interactions are a very effective way of redistributing energy, metals, and magnetic fields in galaxies and of expelling them into intergalactic space when outflows reach escape velocity.
The high-resolution spectrum of Mrk205 combined with H I. Observationally, this is reflected by the fact that all phases of the ISM known to exist in galaxy disks have also been detected in halos. Ram-pressure stripping and tidal interaction are important mechanisms for galaxies to loose their gas. Lyman Spitzer inferred the pressure of hot gas in the Milky Way’s. Thus, current theoretical models of the ISM take into account that gaseous halos are natural extensions of disk ISMs and are heated by the winds and ionizing radiation of massive stars, and by the shock waves of supernovae and their remnants. The first pressure measurement of a galactic atmosphere came in 1956, and it was indirect. The existence, the shapes, and the properties of gaseous halos depend on the level of energy input into the disk ISM per unit surface area, i.e., on the feedback of mass, momentum, and energy produced by vigorous star formation. The X-ray data are consistent with efficient ram pressure stripping of the hot gas halos of early-type galaxies near the group core, but no X-ray tails are. Circumnuclear starbursts are the most energetic flavor of this phenomenon.
Disk-halo interactions occur only above the brightest H II regions, which are found almost exclusively in late-type spirals and dwarf and irregular galaxies. Lasfit is the trusted name in manufacturing the custom fit solutions of auto LED lighting, TPE floor mats, off-road parts, heavy-duty jump starter.
The implications of these results on our understanding of the structure of the interstellar medium (ISM) in our Galaxy and external spiral galaxies, with particular emphasis on the halo ISM, are discussed. This article reviews the most recent observational results on disk-halo interactions in nearby galaxies.
