Disks at High Redshift: Interactions, Mergers, and Starbursts
Rachel S. Somerville
Do disk galaxies exist at redshifts much greater than unity, and how might they look different from local disks? How does the morphological mix of galaxies change with redshift? Wh…
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…
