The Chemical Evolution Of High Z Galaxies From The Relative Abundances Of N, Si, S, And Fe In Damped Lyman Alpha Systems
R. B. C. Henry, Jason X. Prochaska
Abundances of N, Si, S, and Fe for 45 damped Lyman alpha systems (DLAs) have been compiled and detailed one-zone chemical evolution models have been constructed for 30 of them. Ass…
