Comparisons of the Emission-Line and Continuum Properties of Broad Absorption Line and Normal Quasi-stellar Objects
TL;DR: In this article, the emission-line and continuum properties of a set of broad absorption line QSOs and 29 normal BALs (i.e., non-BALs) are compared.
Journal ArticleDOI
A High Signal-to-Noise Ratio Composite Quasar Spectrum

TL;DR: A very high signal-to-noise ratio (S/N of about 400) composite spectrum of the rest-frame ultraviolet and optical region of high luminosity quasars is presented in this article.
Journal ArticleDOI

TL;DR: In this paper, a large-scale ground-based optical spectroscopy and photometry of the variable Seyfert 1 galaxy NGC 5548 undertaken in support of an IUE monitoring campaign is described.
Journal ArticleDOI
Absorption Lines in the Spectra of Quasistellar Objects
TL;DR: In this paper, it was pointed out that the large increase in both the quality and quantity of QSO absorption line data over the last four years has been in large measure due to the development of excellent high-resolution detectors, e.g. the IPCS (Boksenberg 1972).
Journal ArticleDOI
Low-ionization broad absorption lines in quasars
TL;DR: In this article, the absorption line properties of six Mg II broad absorption line quasars (BALQs) are examined using a BALQ sample of Weymann et al.
