Highly-Ionized Gas in the Galactic Halo: A FUSE Survey of O VI Absorption toward 22 Halo Stars
J. Zsargo, K. R. Sembach, J. C. Howk +1
Far Ultraviolet Spectroscopic Explorer spectra of 22 Galactic halo stars are studied to determine the amount of O VI in the Galactic halo between ~0.3 and \~10 kpc from the Galacti…
Ionized Gas in the First 10 kpc of the Interstellar Galactic Halo
J. Christopher Howk, Kenneth R. Sembach, Blair D. Savage
We present FUSE observations of the post-asymptotic giant branch star von Zeipel 1128 (l=42.5, b=+78.7; z=10.0 kpc), located in the globular cluster Messier 3. The FUSE observation…
A FUSE Survey of Molecular Hydrogen in Intermediate-Velocity Clouds in the Milky Way Halo
P. Richter, B. P. Wakker, B. D. Savage +1
Far Ultraviolet Spectroscopic Explorer (FUSE) data is used to investigate the molecular hydrogen (H_2) content of intermediate-velocity clouds (IVCs) in the lower halo of the Milky…
Origins of the Highly Ionized Gas along the Line of Sight towards HD 116852
Andrew J. Fox, Blair D. Savage, Kenneth R. Sembach +5
We present Hubble Space Telescope Imaging Spectrograph (HST/STIS) and Far Ultraviolet Spectroscopic Explorer (FUSE) observations of high ion interstellar absorption along the sight…
Probing Baryons in Galactic Halos and Gas Near Galaxies
K. R. Sembach, B. P. Wakker, B. D. Savage +2
We describe an extensive FUSE survey of highly ionized oxygen in the vicinity of the Milky Way that serves as an example of the type of study that would be desirable for other gala…
Distribution and Kinematics of O VI in the Galactic Halo
B. D. Savage, K. R. Sembach, B. P. Wakker +6
FUSE spectra of 100 extragalactic objects are analyzed to obtain measures of O VI absorption along paths through the Milky Way thick disk/halo. Strong O VI absorption over the appr…
