Abstract We will investigate the disk-halo interaction in four actively star forming edge-on spiral galaxies using the ACS. In recent years considerable progress has been achieved in testing the disk-halo interaction scenario which describes the large scale mass exchange of the ISM between disk and halo including the metal enrichment of the IGM, which is on galactic scales described by various theoretical models (e.g., galactic fountains, chimneys, superwinds). The investigation of nearby edge- on spirals in this respect offers a particularly exciting perspective for a quantitative understanding of this feedback provided by star formation on the ISM. Feedback is the crucial ingredient in all models of galaxy formation and evolution. While commonly implemented in simple terms (global energy or metal injection), further progress can only be achieved with a better understanding of the relevant physics. This requires high spatial resolution studies of nearby galaxies. Whereas groundbased observations are perfectly suited to study the overall morphology of the outflowing gas, they are inadequate to describe the structure on the smallest relevant scales. However, it is the small scale structure that constrains the microphysics to be applied in theoretical models of a multiphase medium. Galaxies spanning a wide range of star formation activity have to be investigated in order to test which processes for the gas ejection are at work. High spatial resolution studies, as can be achieved with the ACS onboard HST and yielding a spatial resolution of 3-7 parsecs for the four proposed target galaxies, will critically test the existing models for the feedback process. ------------------------------------------------------------------------------------ 10416( 4) - 11/22/04 14:57 - [ 2] Observations Description ------------------------ ACS imaging of four actively star forming galaxies. All four targets will be observed in one pointing each. Halpha and R band observations are straight- forward. Specifc orientation angles are chosesn to maximize the visibility of the extended emission as seen from previous ground-based observations.
