Abstract 9618319 Novak This CAREER Program award provides long-term support to measure the magnetic field configuration of the nucleus of our galaxy. The technique used deduces the direction of the fields by measuring the polarization of submillimeter emission from gas and dust near the core of the galaxy. Long grains of dust align themselves with magnetic field, which leads to a net polarization of the emitted far-infrared radiation. Maps of the morphology of the fields will sensitively test models of galactic formation. The project is particularly cost effective because it will make use of a telescope which will be at South Pole for other purposes and will extend its usefulness to over-winter operation. As is expected in all CAREER awards, graduate and undergraduate students are involved with the hands-on experimental aspects of this challenging experiment, including working at South Pole. ***

摘要9618319诺瓦克这个职业计划奖为测量我们银河系核心的磁场配置提供了长期支持。使用的技术通过测量星系核心附近气体和尘埃发出的亚毫米辐射的偏振来推断磁场的方向。长长的尘埃颗粒与磁场对准，导致发射的远红外辐射的净偏振。这些区域的地形图将敏感地测试星系形成的模型。该项目特别具有成本效益，因为它将利用位于南极的望远镜用于其他目的，并将其用途扩大到越冬作业。正如在所有职业奖项中预期的那样，研究生和本科生都参与了这项具有挑战性的实验的动手实验方面，包括在南极工作。***
