TL;DR: In this article, the fate of interstellar gas heated by energetic radiation and far from the galactic plane is considered, and it is shown that for plausible heating rates a very hot corona forms, separated from the cooler gas in the disk by a conductive boundary layer.
Abstract: The fate of interstellar gas heated by energetic radiation and far from the galactic plane is considered. It is shown that for plausible heating rates a very hot corona forms, separated from the cooler gas in the disk by a conductive boundary layer. For heating rates exceeding a critical value a galactic wind is set up, as first shown by Mathews and Baker for elliptical galaxies. Such winds may fill the intracluster space in clusters of galaxies; further heating may drive a cluster wind, as shown by Yahil and Ostriker. It is believed that the flow problem of intracluster gas in the presence of intercluster gas is not yet adequately solved. A variety of observations at X-ray and ultraviolet wavelengths are needed to resolve these questions.

TL;DR: In this paper, Chen et al. further developed the method of identifying absorption line systems in QSO spectra and applied it to PKS 0528-250, and gave two new absorption line system Za = 0.065 and 0.0345, consistent with the systems A1A2, B, C of Norton et al., but the systems D1, D2, E, F and G of Chen and Norton (1984).
