CAREER: Optimizing POLAR Array for CMB Lensing/Delensing

这一职业奖项将使郭博士和他的团队能够开发有助于极阵列设计的技术。极地阵列将是一个地面阵列，将探测和表征宇宙微波背景(CMB)中的极化信号，宇宙微波背景是宇宙学中最可靠和最强大的探测器之一。通过对这一大爆炸残骸的研究，已经确定了许多宇宙学参数。该提案的技术开发部分包括焦平面的设计、探测器/馈电天线体系结构、读出电子学、实现大冷光学的技术以及大口径红外过滤。所有这些都是为了最大化极地阵列的科学产出。该奖项的更广泛影响包括本科生、研究生和博士后的培养。该阵列获得的数据将作为关于高红移质量分布的遗留数据集，这将使整个天文学社区受益。郭博士和他的团队还将与参加斯坦福大学RET项目的教师合作。

This CAREER award will enable Dr. Kuo and his team to develop technology that will assist in the design of the POLAR array. The POLAR array will be a ground-based array that will detect and characterize the polarization signal in the cosmic microwave background (CMB), one of the most reliable and powerful probes in cosmology. Many cosmological parameters have been determined through the study of this remnant of the Big Bang. The technology development components of the proposal include the design of the focal plane, the detector/feed antenna architecture, readout electronics, techniques to implement large cold optics, and large aperture infrared filtering. All of these have the goal of maximizing the scientific output of the POLAR array.The broader impacts of the award include the training of undergraduate, graduate, and post-doctoral students. Data obtained by the array will serve as a legacy data set on the high-redshift mass distribution which will benefit the entire astronomical community. Dr. Kuo and his team will also work with teachers that take part in a RET program at Stanford.
