    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 ...
