Quasars: General, Surveys

Scientific paper

We obtained CCD spectra for 24 stellar objects selected from the Case Low-Dispersion Northern Sky Survey. Fourteen are quasars which are bright enough for future absorption-line studies. Seven of these show a multitude of metallic absorption lines. The quasar redshifts range from z = 0.275 to z = 2.96 with a median of z = 2.15. Two objects are Seyfert galaxies. One object has a relatively featureless spectrum with no detected strong emission lines, and it may be a BL Lac object. Spectra of seven other objects show them to be Galactic stars.
