[52.01] Mg II Absorbing Galaxies: A Review Paper

C. Churchill, J. Charlton (Penn State)

We review the properties of intervening Mg II absorption line systems over the redshift interval 0.3 to 2.2. We include what is currently known about the overall statistical properties of the absorber population, the galaxies associated with the absorbers, the kinematics of the low ionization gas, the associated neutral hydrogen and higher ionization gas (esp. C~IV), and the multiphase ionization conditions. Further details can be found in the poster presentations of Mellon et al., Rigby et al., and Charlton et al.

We briefly discuss the implications for scenarios of galaxy evolution from the perspective of Mg II absorption line studies based upon the evolution in the properties of the absorbers. We also present our plans to extend these studies to z~4 using a moderatly high-resolution, near-infrared spectrograph on the Hobby-Eberly Telescope.

This work is a synopsis of an Invited Review paper to appear in PASP in early 2000. We acknowledge support from NSF grant AST 96-17185, NASA LTSA grant NAG5-6399, and AR-07983.01-96A from STScI, which is operated by AURA, Inc., under NASA contract NAS5-26555.
