Collaborative Proposal: Resolved Mid-IR Observations & Modeling of AGN and their Hosts

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。研究人员将对附近活动星系核（AGN）进行高空间分辨率的中红外成像、光谱和偏振测量，利用8-10m望远镜提供的亚弧秒、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环核气体/尘埃环的光谱能量分布（即亮度与波长），并将数据与该发射的详细模型进行比较。该小组在直径10.4米的加那利望远镜（GTC）上使用偏振相机CanariCam，有大量的保证时间。该项目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员的培训。这项研究将增强我们对活动星系核周围的理解，特别是被认为根据方向阻挡来自中心区域的光的环面。

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.
