Submillimeter Polarimetry

AST-9619186亚毫米旋光仪。芝加哥大学罗杰·希尔德布兰德博士最近开发的仪器使人们有可能在更多的点上观测星际云发射的亚毫米波长的偏振，并获得比以前更高的精度和空间分辨率。希尔德布兰德博士现在将利用这一能力，利用位于夏威夷的加州理工学院亚毫米天文台的仪器，绘制几种类型星际云的偏振图。主要目标是推断这些物体中磁场的形状。第二个目标是研究导致偏振发射的尘埃颗粒对齐的机制。=

AST-9619186 Submillimeter Polarimetry. Instrumentation recently developed by Dr. Roger Hildebrand at the University of Chicago has made it possible to observe the polarization of the submillimeter wavelength emission from interstellar clouds at more points and with better precision and spatial resolution than has been possible before. Dr. Hildebrand will now exploit this capability by using the instrumentation at the California Institute of Technology Submillimeter Observatory in Hawaii to make maps of polarization in several types of interstellar clouds. The primary goal is to infer the shapes of the magnetic fields in these objects. A secondary goal is to investigate the mechanism that aligns the dust grains responsible for the polarized emission. ==============================
