This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The investigators will carry out high spatial resolution mid-infrared imaging, spectroscopy, and polarimetry of nearby active galactic nuclei (AGN), taking advantage of the subarcsecond, diffraction limited resolution afforded by 8-10m telescopes to probe the inner regions of AGN. The main goal is to elucidate the spectral energy distribution (i.e., the brightness versus wavelength) of the circumnuclear gas/dust torus in the infrared region, and compare the data to detailed models for this emission. The group has substantial guaranteed time using their polarimetric camera CanariCam on the 10.4m-diameter Gran Telescopio CANARIAS (GTC).Broader impacts of this program include developing international collaborations, archival data release, bilingual outreach, and training of graduate students and a postdoctoral researcher. The research will enhance our understanding of the environs of active galactic nuclei, particularly the torus thought to block the light from the central region depending on orientation.

该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。研究人员将对附近的活动星系核（AGN）进行高空间分辨率中红外成像、光谱学和偏振测量，利用8-10m望远镜提供的亚角秒、衍射极限分辨率来探测AGN的内部区域。 主要目标是阐明红外区域核周气体/尘埃环面的光谱能量分布（即亮度与波长），并将数据与这种发射的详细模型进行比较。 该小组有充足的时间保证在直径 10.4m 的 Gran Telescopio CANARIAS (GTC) 上使用其偏振相机 CanariCam。该项目的更广泛影响包括发展国际合作、档案数据发布、双语推广以及研究生和博士后研究员的培训。 这项研究将增强我们对活动星系核周围环境的理解，特别是被认为根据方向阻挡来自中心区域的光线的环面。
