Abstract (from CDS):

Near-infrared spectra of 13 QSOs located between 4.4<z<5.3 were obtained by the OH-airglow suppression spectrograph mounted on the Subaru telescope. The Fe II/Mg II emission-line ratios of the QSOs at various redshifts were examined by applying the same fitting algorithm to the present data together with published or archived spectra. We found a trend of a decreasing Fe II/Mg II ratio from z∼5 to 1.5, almost independent of their luminosities. We also confirmed the Baldwin effect on the Mg II emission line.
