标题： Submillimeter Imaging of NGC 891 with SHARC

摘要： 亚毫米波长阵列相机在大型地面望远镜上的应用正在革新这些波长的成像，使高分辨率的亚毫米波尘埃发射调查成为可能，在恒星形成区域和星系中。 在这里，我们呈现了最近获得的350微米的边缘星系NGC 891图像，该图像使用了加州理工学院亚毫米观测站（CSO）的亚毫米高角分辨率相机（SHARC）。 我们发现高分辨率的亚毫米数据是较短波长卫星数据的重要补充，这使得能够可靠地将毫米波长看到的冷尘埃成分与主导远红外（FIR）光度的温暖成分分开。 显示英文摘要

摘要： The advent of submillimeter wavelength array cameras operating on large ground-based telescopes is revolutionizing imaging at these wavelengths, enabling high-resolution submillimeter surveys of dust emission in star-forming regions and galaxies. Here we present a recent 350 micron image of the edge-on galaxy NGC 891, which was obtained with the Submillimeter High Angular Resolution Camera (SHARC) at the Caltech Submillimeter Observatory (CSO). We find that high resolution submillimeter data is a vital complement to shorter wavelength satellite data, which enables a reliable separation of the cold dust component seen at millimeter wavelengths from the warmer component which dominates the far-infrared (FIR) luminosity.
