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

AST-0545405Lubin该项目由探索性研究小额拨款计划支持，旨在使用安装在White Mountain Barcroft设施中的工作原型来测试偏振调制方案。这项测试是必要的，因为担心该方法可能存在的系统性偏差和其他缺点。未来的目标是在北半球和南半球的多个地点大规模部署望远镜阵列，以测量宇宙微波背景(CMB)的偏振各向异性中的所谓B模或卷曲模。开发和测试这一重要科学的多种方法是很重要的，这项温和的试验将指导CMB研究的未来大规模努力。该小组有很好的记录，让学生参与实验物理和观测天体物理，造福所有人，并包括教育和扩展到高中和社区大学，作为他们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.
