Spectroscopy of ten quasars obtained with the Goddard High Resolution Spectrograph (GHRS) of the Hubble Space Telescope (HST) is presented. We detect 357 absorption lines above a significance level of 3σ in the ten sightlines, and 272 lines above a significance level of 4.5σ. Automated software is used to detect and identify the lines, almost all of which are unresolved at the GHRS G140L resolu...

We present Goddard High Resolution Spectrograph and ORFEUS-II measurements of Si IV, C IV, N V, and O VI absorption in the interstellar medium of the Galactic disk and halo toward the nucleus of the Seyfert galaxy ESO141-055. The high ionization absorption is strong, with line strengths consistent with the spectral signature expected for hot (T ∼> 10 K) collisionally ionized gas in either a “Ga...

We present interstellar absorption line measurements of the ions S III and Al III towards the stars β Sco, μ Col, ξ Per, ζ Oph, ρ Leo, and HD 18100 using archival data from the Goddard High Resolution Spectrograph on board the Hubble Space Telescope. The ions Al III and S III trace heavily depleted and non-depleted elements, respectively, in ionized gas along the sightlines to these late-O/earl...

High resolution spectra of the old nova V 603 Aql (1918) were taken in the regions of the C iv, Nv and Si iv resonance doublets, using the G160M grating of the GHRS on board the Hubble Space Telescope. No sign of sharp absorption components due to the envelope ejected in 1918 is present. If spherical symmetry is assumed, the estimated upper limits to the column densities indicate a maximum enve...

We present spectroscopic observations for quasars Q0107−025A, Q0107−025B, and Q0107−0232. For the first time, all data obtained with the Hubble Space Telescopes GHRS and FOS for these three quasars are combined. Lyα absorbers selected from the spectra can be used to trace the coherence of the intergalactic medium (IGM) on scales of 1−2 h 70 Mpc over the redshift range 0.4 < za < 0.9. A new anal...
