We present a high resolution (FWHM= 2.7 km s −1 ), high S/N echelle spectrum for the zem = 2.26 QSO J2123−0050 and determine elemental abundances for the zabs = 2.06 subDLA in its line of sight. This high redshift sub-DLA has a complex kinematic structure and harbours detections of neutral (Si, Ci), singly (e.g. Cii, Sii) and multiply ionized (e.g. Civ, Siiv) species as well as molecular H2 and HD. The plethora of detected transitions in various ionization stages is indicative of a complex… Expand
