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…
Molecular Hydrogen in High-Velocity Clouds
Philipp Richter, Kenneth R. Sembach, Bart P. Wakker +1
We present Far Ultraviolet Spectroscopic Explorer (FUSE) observations of interstellar molecular hydrogen (H_2) in two Galactic high-velocity clouds (HVCs). Molecular hydrogen absor…
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…
Molecular Gas in the Galactic Halo and Beyond
Philipp Richter
I review recent observations of molecular gas in the halo of the Milky Way and in the Magellanic Clouds. Far-ultraviolet absorption line studies of molecular hydrogen (H_2) with OR…
The Diversity of High- and Intermediate-Velocity Clouds: Complex C versus IV Arch
P. Richter, K. R. Sembach, B. P. Wakker +5
We present Far Ultraviolet Spectroscopic Explorer (FUSE) and Space Telescope Imaging Spectrograph (STIS) observations of interstellar ultraviolet absorption lines in the Galactic h…
