CAREER: Submillimeter Polarimetry of the Galactic Nucleus

摘要：9618319 Novak这个职业计划奖为测量银河系核心的磁场结构提供了长期的支持。所使用的技术通过测量靠近星系核心的气体和尘埃的亚毫米辐射的偏振来推断出场的方向。尘埃的长颗粒与磁场对齐，这导致发射的远红外辐射的净极化。磁场的形态图将灵敏地检验星系形成的模型。该项目特别具有成本效益，因为它将利用将在南极为其他目的而设的望远镜，并将其用途扩大到越冬作业。正如所有职业奖所期望的那样，研究生和本科生都参与了这个具有挑战性的实验的动手实验方面，包括在南极工作。* * *

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. ***
