Comparing Chemical Abundances of the Damped Lya Systems and Metal-Poor Stars
Jason X. Prochaska
I briefly draw comparisons between the fields of damped Lya and metal-poor stellar abundances. In particular, I examine their complementary age-metallicity relations and comparison…
Chemical Abundances in the Damped Lya Systems
Jason X. Prochaska
I introduce and review the data and analysis techniques used to measure abundances in the damped Lya systems, quasar absorption-line systems associated with galaxies in the early U…
Damped Ly-alpha Systems in Semi-Analytic Models: Sensitivity to dynamics, disk properties, and cosmology
Ariyeh H. Maller, Rachel S. Somerville, Jason X. Prochaska +1
Previously we have shown that it is possible to account for the kinematic properties of damped Lyman alpha systems (DLAS) in the context of semi-analytic models. In these models, h…
Optical Counterparts to Damped Lyman Alpha Systems
Ariyeh H. Maller, Jason X. Prochaska, Rachel S. Somerville +1
Previously we have shown (Maller et al, 1998) that the kinematics of Damped Lyman Alpha Systems (DLAS) as measured by Prochaska and Wolfe (1998) can be reproduced in a multiple dis…
What Damped Ly-alpha Systems Tell Us About the Radial Distribution of Cold Gas at High Redshift
Ariyeh H. Maller, Jason X. Prochaska, Rachel S. Somerville +1
We investigate the properties of damped Lyman-alpha systems (DLAS) in semi-analytic models, focusing on whether the models can reproduce the kinematic properties of low-ionization…
