SGER: Experimental Investigation of Observing Techniques Proposed for the B-Machine

AST-0545405 Lubin该项目由探索性研究计划小额赠款资助，旨在使用安装在白色山Barcroft设施的工作原型测试偏振调制方案。 这项测试是必要的，因为担心可能的系统性偏差和该方法的其他缺点。 未来的意图是在北方和南方半球的多个地点部署大量望远镜阵列，以测量宇宙微波背景（CMB）偏振各向异性中的所谓B或卷曲模式。 重要的是要开发和测试这一重要科学的多种方法，这个温和的试验将引导未来在CMB研究的大规模努力。该小组有一个强大的记录，让学生参与实验物理学和观测天体物理学，以造福所有人，并包括教育和推广到高中和社区大学作为其宇宙学研究的内在组成部分。

AST-0545405LubinThis project, supported under the Small Grant for Exploratory Research program, is intended to test a polarization modulation scheme, using a working prototype installed at the White Mountain Barcroft facility. This test is necessary, because of concerns about possible systematic biases and other shortcomings of the method. The future intent is a large deployment of arrays of telescopes to multiple sites in the northern and southern hemispheres to measure what are called B, or curl, modes in the polarization anisotropy of the Cosmic Microwave Background (CMB). It is important to develop and test multiple approaches to this important science, and this modest trial will steer future large efforts in CMB research.The group has a strong record of involving students with experimental physics and observational astrophysics, to the benefit of all, and includes education and outreach to high schools and community colleges as an intrinsic part of their cosmological research.
