The awardees will carry out a research program on extended emission line regions (EELRs) around quasars, which are thought to be the result of a superwind emanating from the active region. Superwinds may be fundamentally important in limiting the buildup of galaxies via a feedback loop. The primary goals of this research are to: 1) characterize physical conditions in the brighter parts of several EELRs; (2) measure large-scale velocity fields in the EELR gas; (3) measure velocities in emission-line gas close to the QSO; and (4) quantify the relative levels of star formation and nuclear activity in matched samples of QSOs with and without luminous EELRs. The broader impacts include training of research students, undergrad exercises, and public lectures. Also, a dedicated server will improve public access to a photoionization code.

获奖者将在类星体附近的扩展排放线区域（EELR）上执行一项研究计划，这被认为是来自活跃地区的超级风波的结果。超级风波在通过反馈循环限制星系的堆积方面可能至关重要。 这项研究的主要目标是：1）在几个EELR的明亮部分中表征身体状况； （2）测量EELR气体中的大规模速度场； （3）测量接近QSO的发射线气体的速度； （4）量化有或没有发光EELR的QSO的匹配样品中恒星形成和核活性的相对水平。更广泛的影响包括研究学生的培训，本科练习和公开讲座。 此外，专用服务器将改善公共对光电离代码的访问。
