Elemental abundances in the broad emission line region of quasars at redshifts larger than 4
We present observations of 11 high redshift quasars () observed with low spectral resolution in the restframe ultraviolet using FORS 1 at the VLT UT 1. The emission-line fluxes of strong permitted and intercombination ultraviolet emission lines are measured to estimate the chemical composition of the line emitting gas. Comparisons …
