The Interstellar Medium in Galaxies - An Overview

  • G. R. Knapp
Part of the Astrophysics and Space Science Library book series (ASSL, volume 161)


An attempt is made to summarize recent observational developments on the subject of the interstellar medium in galaxies, with emphasis placed on global properties. After a summary of the properties and distribution of the ISM in the solar neighborhood and in the plane of the Galaxy, some results from the most important observational probes (HI, CO and infrared) are described. A recent development is the observation of the ISM in galaxies of all morphological types, early to late; these developments are summarized and the properties of galaxies of different types compared to each other. Finally, the origin of radio galaxies, the effect of environment and the prospect for direct observations of the evolution of the ISM in galaxies are discussed.
