Quasar Broad Absorption Line Variability on Multiyear Timescales
We use quantitative metrics to characterize the variation of C iv [lambda]1549 broad absorption lines (BALs) over 3-6 (rest-frame) years in a sample of 13 quasars at [image] and compare the results to previous studies of BAL variability on shorter timescales. The strong BALs in our study change in c...
