Abstract

We present NIR spectroscopy of emission lines of a sample of five z6 quasars, including fainter objects than observed before. The measured FeII/MgII ratios are around solar and consistent with a lack of evolution of the metallicity of quasar BLRs up to z6, suggesting that stars in their hosts formed at z6. The BH masses, measured from both MgII and CIV line widths are within the range 2-16108M, the smallest found in such distant objects.
