Hot Gas in the Galaxy: how Extensive is It?
Abstract
Observational and theoretical evidence is reviewed concerning the possible extent of hot gas at a temperature of the order of 1 million K in the Galaxy. Consequences of hot gas filling a large fraction of interstellar space for galactic shocks are considered. H I radio observations are discussed along with O VI observations in the UV, soft X-ray observations, and theoretical estimates of the filling factor of hot gas at 1 million K. A series of future radio and soft X-ray observations of external spiral galaxies is proposed.
