We present the wavelength-resolved reverberation mapping (RM) of combined Mg II and UV Fe II broad-line emissions for two intermediate-redshift (z ∼ 1), luminous quasars, HE 0413-4031 and HE 0435-4312, monitored by the Southern African Large Telescope (SALT) and 1m class telescopes between 2012 and 2022. Using a wavelength-resolved technique, we aim to disentangle the Mg II and Fe II emission regions and to build a radius-luminosity (R-L) relation for UV Fe II emission, which has so far remained unconstrained.
