A SURVEY OF Mg II ABSORPTION AT 2 < z < 6 WITH MAGELLAN/FIRE. I. SAMPLE AND EVOLUTION OF THE Mg II FREQUENCY
We present initial results from the first systematic survey for Mg II quasar absorption lines at z > 2.5. Using infrared spectra of 46 high-redshift quasars, we discovered 111 Mg II systems over a path covering 1.9 < z < 6.3. Five systems have z > 5, with a maximum of z = 5.33-the most d...
