Abstract
Comparisons of the kinematics of MgII absorbing gas and the stellar rotation curves in 0.5 ≤ z ≤ 1.0 spiral galaxies suggests that, at least in some cases, the extended gaseous envelopes are dynamically coupled to the stellar matter. A strong correlation exists between the overall kinematic spread of MgII absorbing gas and CIV absorption strength, and therefore kinematics of the higher-ionization gas. Taken together, the data may suggest a “halo/disk connection” between z ∼ 1 galaxies and their extended gaseous envelopes. Though the galaxies in our sample are few in number, there are no clear examples that suggest the gas is accreting/infalling isotropically about the galaxies from the intergalactic medium.
