This program will use archival data from the Very Large Telescope (VLT) and the Keck Observatory to probe quasar winds. It will result in improved statistical studies of the link between the absorption line properties and optical and radio properties of quasars. This will be accomplished by studying intrinsic absorption line systems through their variability and through comparison of photoionization and hydrodynamic model predictions of absorption features with the data.Broader impacts of the work include training of undergrad and graduate students, and outreach to the local community via the established yearly Astrofest, a four night festival of astronomy attracting over 1500 members of the general public each summer.

该程序将使用来自非常大的望远镜（VLT）和凯克天文台的档案数据进行探测。 这将导致对吸收线特性与类星体光学和无线电特性之间联系的统计研究改进。 这将通过研究固有的吸收线系统通过其可变性以及将吸收特征和数据的流体动力模型预测与数据进行比较来实现。BRODER的影响包括对本科生和研究生的培训，以及通过年度Astrofest的既定年度Astrofest，每年的四夜举行的1500次夏季公众的夜晚的Astracherest培训，并通过当地社区进行宣传。
