Abstract:
We present results from an analysis of FUSE spectroscopy of the
zem=0.57 quasar PKS 0405-123. We focus on the intervening metal-line
systems identified along the sight line and investigate their
ionization mechanism, ionization state, and chemical abundances.
Including Hubble Space Telescope STIS spectroscopy, we survey the
entire sight line and identify six O VI absorbers to a 3σ
equivalent width (EW) limit of 60mÅ.
Description:
PKS 0405-123 was observed with the FUSE observatory using the LWRS
apertures with the detectors in TTAG mode during one visit beginning
UT 2001 October 5.
