Scientific paper

We examined 75 high resolution quasar spectra, obtained from the VLT/UVES archive. The quasar redshifts ranged from 0.8 to 4.7. The goal of our survey was to identify and characterize intrinsic absorption line systems. Over 450 CIV, SiIV, and NV doublets were found in a systematic search of the 75 quasar spectra. A partial covering test was carried out on a system by system basis to determine whether or not the system could be demonstrated to be intrinsic (physically associated with the quasar). Most other systems are likely to be intervening (an object that resides within the line of sight of the quasar). The classification scheme being used was described in Misawa 2007, who studied narrow intrinsic absorption in a sample of 37 Keck HIRES quasars, finding that at least 50% of all quasars host intrinsic NALs. Our larger sample, which generally has broader wavelength coverage, enables a study of the relationship between intrinsic narrow absorption lines and quasar properties.
