The Metallicity of Redshift 0.5<z<1 Field Galaxies
C. Marcella Carollo, Simon J. Lilly, Alan Stockton
We are undertaking a program to measure emission line ratios in a selected sample of CFRS starforming galaxies in order to compute their Interstellar Medium metalli…
Low-Ionization BAL QSOs in Ultraluminous Infrared Systems
Gabriela Canalizo, Alan Stockton
Low-ionization broad absorption line (BAL) QSOs present properties that cannot generally be explained by simple orientation effects. We have conducted a deep spectroscopic and imag…
The Oldest Stellar Populations at z ~ 1.5
Alan Stockton
There are at least three reasons for being interested in galaxies at high redshifts that formed most of their stars quite quickly early in the history of the Universe: (1) the ages…
Serendipitous Discovery of a BAL QSO at z = 2.169
Gabriela Canalizo, Alan Stockton, Katherine C. Roth
We report the serendipitous discovery of a BAL QSO at z = 2.169, located 41'' southwest of 3C 48. We present Keck LRIS spectroscopy covering rest frame 1500 A to 2300 A . The C IV…
