Elemental Abundances in the Broad Emission Line Region of Quasars at Redshifts larger than 4
M. Dietrich, I. Appenzeller, F. Hamann +4
We present observations of 11 high redshift quasars ($3.9 \la z \la 5.0$) observed with low spectral resolution in the restframe ultraviolet using FORS 1 at the VLT UT 1. The emiss…

Chemical Abundances in Broad Emission Line Regions: The "Nitrogen-Loud" QSO 0353-383
J. A. Baldwin, F. Hamann, K. T. Korista +3
The intensity of the strong N V 1240 line relative to C IV 1549 or to He II 1640 has been proposed as an indicator of the metallicity of QSO broad emission line regions, allowing a…
