Scientific paper

We present a study of 25 z < 0.4 intergalactic absorption systems with detections of three or more metal ions using spectra of 17 quasars from the Far Ultraviolet Spectroscopic Explorer and the E140M mode of the HST/Space Telescope Imaging Spectrograph.
Previously, we characterized the component structure of the absorption in several ions, O VI, N V, C IV/C III/C II, Si IV/Si III/Si II, S IV/S III/S II, and Fe III/Fe II, and measured the velocity offsets of these ions relative to the Lyman series lines. We found some evidence for multiphase structure. We continue that work here by first expanding our search list to include over 100 ions. We present column density measurements of all the species in these systems, for use in ionization modeling.
