Abstract We present Hubble Space Telescope and Far Ultraviolet Spectroscopic Explorer
observations of the intergalactic absorption toward QSO PG 1116+ 215 in the 900-3000 Å …

We combine a FUSE sample of O VI absorbers (z< 0.15) with a database of 1.07 million
galaxy redshifts to explore the relationship between absorbers and galaxy environments. All …

Far-UV echelle spectroscopy of the radio-quiet QSO H1821+ 643 (z em= 0.297), obtained
with the Space Telescope Imaging Spectrograph (STIS) at∼ 7 km s-1 resolution, reveals …

We report the discovery of an O VI absorption system at z abs= 0.14232 in a high-resolution
FUV spectrum of PG 0953+ 415 obtained with the Space Telescope Imaging Spectrograph …

Intergalactic absorbers along lines of sight to distant quasars are a powerful diagnostic for
the evolution and content of the intergalactic medium (IGM). In this study, we use the Far …

With a column density log N (O vi)= 14.95±0.05, the O vi absorber at z abs≃ 0.2028
observed toward the quasi-stellar object PKS 0312–77 (z em= 0.223) is the strongest yet …

To study the nature of low-z Ly α absorbers in the spectra of QSOs, we have obtained high
signal-to-noise ratio (S/N) UV spectra of H1821+ 643 (z em= 0.297) and PG 1116+ 215 (z …

We report observations from the Hubble Space Telescope (HST) and the VLA on the
galactic environment, metallicity, and D/H in strong low-redshift Ly α absorption systems …

We present the first detailed analysis of the chemical abundances, ionization state, and
origin of a partial Lyman limit system [N (H)≈ 10 16 cm-2] at low redshift (z= 0.167 toward …

We have conducted a deep long-slit spectroscopic search for high-redshift (2.7< z< 4.7) Lyα
emission. Four pairs of deep, high-resolution (R≈ 2000), long-slit CCD frames were taken at …
