Understanding Quasar Central Engines Using Narrow Intrinsic Absorption Lines

该计划将使用来自甚大望远镜（VLT）和凯克天文台的档案数据来探测类星体风。 这将导致改进对类星体的吸收线特性与光学和无线电特性之间联系的统计研究。 这将通过研究固有吸收线系统的可变性以及通过比较光电离和流体动力学模型对吸收特征的预测与数据来实现。这项工作的更广泛影响包括对本科生和研究生的培训，以及通过既定的年度Astrofest向当地社区推广，每年夏季，天文节共举行四晚，吸引超过一千五百名市民参加。

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.
