[35.04] The Hot ISM/IGM - New Insights from the Far Ultraviolet Spectroscopic Explorer

K. R. Sembach (Johns Hopkins University)

The Far Ultraviolet Spectroscopic Explorer (FUSE) is providing new insights into hot gas in the Milky Way and the low-redshift universe. The widespread existence of hot gas in the halo of the Milky Way has implications for understanding the transport of matter and energy out of the thin disk, the circulation of the interstellar medium, and the cycles of star formation in galaxies. A hot Galactic halo also serves as a potential site for encounters with gas in the vicinity of the Galaxy. Such interactions provide opportunities for studying material within the Local Group and its effects on Galactic chemical evolution. Hot gas in the low-redshift intergalactic medium may also serve as a significant reservoir of baryonic material. In this talk, I will comment briefly on early FUSE observations related to these topics.

This work is based on data obtained for the Guaranteed Time Team by the NASA-CNES-CSA FUSE mission operated by the Johns Hopkins University. Financial support has been provided by NASA contract NAS5-32985.
