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