摘要

Bicep/Keck阵列实验是一系列小孔径折射望远镜,从南极观测度尺度的宇宙微波背景偏振,以寻找原始b模特征。作为一对差分实验,必须控制的一个重要系统是同置的正交极化探测器之间的差分光束响应。我们使用高保真的光束响应原位测量来估计我们最新数据中的温度-偏振(T→P)泄漏,包括2016年至2018年的观测数据。这包括三年的Bicep3在95千兆赫的观测,以及来自凯克阵列的多频数据。在这里,我们展示了这些接收器的带平均远场波束图、差分波束失配和剩余波束功率(通过去投影滤除领先的差模后)。我们展示了“波束图模拟”的初步结果,它使用这些波束图来观察模拟温度(无Q/U)天空,以估计我们实际数据中的T→P泄漏。

Analysis of Temperature-to-Polarization Leakage in BICEP3 and Keck CMB Data from 2016 to 2018
The Bicep/Keck Array experiment is a series of small-aperture refracting telescopes observing degree-scale Cosmic Microwave Background polarization from the South Pole in search of a primordial B-mode signature. As a pair differencing experiment, an important systematic that must be controlled is the differential beam response between the co-located, orthogonally polarized detectors. We use high-fidelity, in-situ measurements of the beam response to estimate the temperature-to-polarization (T → P) leakage in our latest data including observations from 2016 through 2018. This includes three years of Bicep3 observing at 95 GHz, and multifrequency data from Keck Array. Here we present band-averaged far-field beam maps, differential beam mismatch, and residual beam power (after filtering out the leading difference modes via deprojection) for these receivers. We show preliminary results of "beam map simulations," which use these beam maps to observe a simulated temperature (no Q/U) sky to estimate T → P leakage in our real data.
