Exploring Hot Gas in the Galactic Halo and High Velocity Clouds
Kenneth R. Sembach, Bart P. Wakker, Blair D. Savage +1
In the five years since its launch, the Far Ultraviolet Spectroscopic Explorer has given the astronomical community a marvelous glimpse into the realm of previously unexplored regi…
High-velocity OVI in and near the Milky Way
Bart P. Wakker, Blair. D. Savage, Kenneth R. Sembach +2
The Far Ultraviolet Spectroscopic Explorer (FUSE) has observed over three hundred fifty sightlines to extragalactic targets. About one hundred fifty of these are of sufficient qual…
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…
FUSE Observations of Degree-Scale Variations in Galactic Halo O VI
J. Christopher Howk, Blair D. Savage, Kenneth R. Sembach +1
We report Far Ultraviolet Spectroscopic Explorer (FUSE) observations of interstellar O VI absorption in the halo of the Milky Way towards 12 early-type stars in the Large Magellani…
FUSE Observations of O VI Overlying the Scutum Supershell
N. C. Sterling, B. D. Savage, P. Richter +2
We present Far Ultraviolet Spectroscopic Explorer observations of the B0 III star HD 177989 ( = 4.9 kpc). This line of sight passes through t…
FUSE and STIS Observations of Intervening OVI Absorption Line Systems in the Spectrum of PG0953+415
B. D. Savage, K. R. Sembach, T. M. Tripp +1
We present FUSE and STIS observations of the IGM toward PG 0953+415 (z_em = 0.239). An O VI system at z = 0.06807 is detected in H I Lya, Lyb, Lyg, O VI N V, C IV, and C III. The o…
