ABSTRACT 9409130 KAY, Laura In 'unified models' of Active Galactic Nuclei, orientation effects play a large role in determining what we see and thus how we classify a given object. One of the missing pieces in these models is the identification of Narrow-Line (Type 2) QSO's. Optical spectropolarimetry has been used successfully to show that some Type 2 AGN are in fact obscured Type 1 (Broad and Narrow-Line)AGN. For this project, the principal investigator will use spectropolarimetry to study 'superluminous' and ultraluminous' Type 2 AGN identified by IRAS to see if some of them harbor a Type I QSO nucleus identifiable only in scattered, and thus polarized, light. If a collection of such obscured quasars is identified, then complementary observations in infrared and possibly with HST will be planned. Undergraduate students from Barnard College will participate in this project through independent study during the academic year or as summer students.

摘要 9409130 KAY，Laura 在活动星系核的“统一模型”中，方向效应在确定我们所看到的以及我们如何对给定物体进行分类方面起着重要作用。 这些模型中缺少的部分之一是窄线（2型）类星体的识别。 光学偏振光谱法已经成功地证明了一些2型活动星系核实际上被1型活动星系核（宽线和窄线）所遮蔽。 在这个项目中，主要研究者将使用分光偏振法来研究IRAS识别的“超亮”和超亮的“2型活动星系核”，看看其中一些是否含有只能在散射光中识别的I型类星体核，因此偏振，光。 如果这些被遮蔽的类星体的集合被识别出来，那么将计划在红外线和可能的HST中进行补充观测。 巴纳德学院的本科生将在学年期间通过独立学习或作为暑期学生参与该项目。
