摘要
我们表明，通过考虑准星透镜引起的吸收线槽变化， can obtain invaluable information on the structure of quasar outflows. Depending on the structure and geometry of the outflowing gas, such extrinsic line variability can be manifested as changes to the equivalent width of the line as well as line profile distortions. Here we consider several physically distinct outflow models, having very similar spectral predictions, and show how ML induced absorption line variability can be used to distinguish between them. The merits of future systematic studies of these effects are exemplified.
