What can the occult do for you?
摘要：
星际尘埃仍然是天文学中的主要不确定性，限制了例如，宇宙学距离估计和光如何在星系内重新处理的模型。当一个前景星系偶然地与一个更远的星系重叠时，后者会照亮更近的前景星系中的尘埃结构。这样的重叠或掩星星系对可以用来测量最近星系中尘埃的分布，具有很高的精度。STARSMOG计划使用哈勃望远镜绘制前景星系中尘埃的分布，细节<100 pc。积分场单元（IFU）观测将绘制有效消光曲线，解开精细尺度几何形状和颗粒组成对光穿过星系的路径的作用。重叠星系技术有望提供对星系中尘埃的清晰理解：几何形状，作为星系质量和半径函数的变暗概率函数，以及其对波长的依赖性。
英文摘要：
Interstellar dust is still a dominant uncertainty in Astronomy, limiting precision in e.g., cosmological distance estimates and models of how light is re-processed within a galaxy. When a foreground galaxy serendipitously overlaps a more distant one, the latter backlights the dusty structures in the nearer foreground galaxy. Such an overlapping or occulting galaxy pair can be used to measure the distribution of dust in the closest galaxy with great accuracy. The STARSMOG program uses Hubble to map the distribution of dust in foreground galaxies in fine (<100 pc) detail. Integral Field Unit (IFU) observations will map the effective extinction curve, disentangling the role of fine-scale geometry and grain composition on the path of light through a galaxy. The overlapping galaxy technique promises to deliver a clear understanding of the dust in galaxies: geometry, a probability function of dimming as a function of galaxy mass and radius, and its dependence on wavelength.
