The Qz5 Survey (II): Metallicity Evolution of Damped Lyα Systems Out to z$\sim$5

Marie Wisz, Marc Rafelski, Grecco Oyarzun +10

Damped Ly$\alpha$ absorbers (DLAs) are the highest \HI\ column density (\NHI) absorption line systems detected in the spectra of background quasars. DLAs dominate the neutral gas conten…
