Echelle spectrograph observations of the Hubble Deep Field South QSO J2233--606

Abstract

We report on high-resolution observations (R=35 000) of the Hubble Deep Field South QSO J2233-606 obtained with the University College London Echelle Spectrograph at the Anglo-Australian Telescope. We present spectral data for the wavelength region 3530 3700 A. Voigt profiles are fitted to determine the redshift and column densities of the observed features. Eight heavy-element intervening systems are identified, as well as an associated system showing evidence for incomplete coverage of the background source.
