Early metal enrichment in high-redshift quasars
R. Maiolino
Quasars are powerful systems whose spectrum is rich of metal features that allow us to investigate the chemical evolution of galaxies at very high redshift, even close to the reion…

The metallicity of the most distant quasars
Y. Juarez, R. Maiolino, R. Mujica +5
We investigate the metallicity of the broad line region (BLR) of a sample of 30 quasars in the redshift range 4<z<6.4, by using near-IR and optical spectra. We focus on the ratio o…
