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.

获奖者将开展一项关于类星体周围扩展发射线区域（EELR）的研究计划，这些区域被认为是活动区域发出的超级风的结果。超级风可能是通过反馈回路限制星系形成的根本重要因素。 这项研究的主要目标是：1）描述几个EELR较亮部分的物理条件; 2）测量EELR气体中的大尺度速度场; 3）测量类星体附近发射线气体中的速度; 4）量化有和没有发光EELR的类星体匹配样本中星星形成和核活动的相对水平。更广泛的影响包括研究生的培训，本科生的练习和公开讲座。 此外，专用服务器将改善公众对光电离代码的访问。
