This award supports continuation of work begun under a Small Grant for Exploratory Research. The heart of the work is the utilization of an important new astronomical instrument, a spectropolarimeter at the Palomar five meter telescope, to study the nuclei of active galaxies. The use of polarimetry enables one to infer properties of the central object of such systems, even when they are obscured by intervening dust in the parent galaxy. This instrument was designed, built, and will be operated by the group that has led the way in the study of apparent superluminal motion in some of these objects.

该奖项支持在探索性研究小额赠款下开始的工作的继续。这项工作的核心是利用一种重要的新天文仪器，帕洛玛5米望远镜上的分光偏振计，来研究活动星系的核心。利用偏振法可以推断出这些星系中心物体的性质，即使它们被母星系的尘埃所遮挡。这台仪器的设计、制造和操作，都是由在某些天体的超光速运动研究方面处于领先地位的团队负责的。
