Constraining Variationsin the Fine-Structure Constant, Quark Massesand the Strong Interaction
We present evidence for variations in the fine-structure constant from Keck/HIRES spectra of 143 quasar absorption systems over the redshift range 0.2 < zabs < 4.2. This includes 15 new systems, mostly at high-z ...

The First Detection of Cobalt in a Damped Lyman Alpha System
We present the first ever detection of Cobalt in a Damped Lyman Alpha system (DLA) at z ~ 2. In addition to providing important clues to the star formation history of these high redshift galaxies, we discuss how ...
