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.

该奖项是根据2009年《美国复苏和再投资法案》(公法111-5)提供资金的。研究人员将对附近的活动星系核(AGN)进行高空间分辨率的中红外成像、光谱和偏振测量，利用8-10米望远镜提供的亚弧秒衍射有限分辨率来探测AGN的内部区域。主要目的是阐明红外区核周气体/尘埃环的光谱能量分布(即亮度与波长的关系)，并将数据与这种发射的详细模型进行比较。该小组在直径10.4米的Gran Telescopio Canarias(GTC)上使用他们的偏振相机CanariCam的时间得到了很大的保证。该计划的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人员的培训。这项研究将加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央区域的光的环状结构。
