The Qz5 Survey (II): Metallicity Evolution of Damped Lyα Systems Out to z5
Marie Wisz, Marc Rafelski, Grecco Oyarzun +10
Damped Ly absorbers (DLAs) are the highest \HI\ column density (\NHI) absorption line systems detected in the spectra of background quasars. DLAs dominate the neutral gas conte…

A positive correlation between broad HI Ly absorptions and local overdensities of galaxies
Ismael Pessa, Nicolas Tejos, Karen Martinez-Acosta +3
A large fraction of the baryon budget at resides in large-scale filaments in the form of diffuse intergalactic gas, and numerous studies have reported a significant correlati…
