This program will analyze over 100 IRS archival spectra from the Spitzer Space Telescope with the objective of understanding infrared emission from dust structures in active galactic nuclei (AGN). The investigation will address a number of important questions about dust in AGN, and will determine if the simplistic dust torus plus orientation explanation for the differences between Seyfert Type 1 and Type 2 galaxies requires significant revision.Broader impacts of the work include training of undergrad and graduate students, and outreach to local K-12 schools by educating students on cutting-edge astronomy topics.

该项目将分析来自斯皮策太空望远镜的100多个IRS档案光谱，目的是了解活动星系核（AGN）尘埃结构的红外发射。这项研究将解决关于AGN中尘埃的一些重要问题，并将确定是否需要对Seyfert 1型和2型星系之间差异的简单的尘埃环加方向解释进行重大修改。这项工作的更广泛影响包括对本科生和研究生的培训，以及通过教育学生前沿天文学主题，向当地K-12学校推广。
