宇宙前景探测器（COFE）：一个描述偏振前景的球载微波偏振计
The Cosmic Foreground Explorer (COFE): A balloon-borne microwave polarimeter to characterize polarized foregrounds
摘要：
COsmic Foreground Explorer（COFE）是一种球载微波偏振仪，用于测量主导漫射偏振前景的低频和低l特性。从北半球和南半球进行的短时间气球飞行将使望远镜覆盖80%的天空，在10 GHz至20 GHz的范围内，每像素的预期灵敏度优于100 $μK / deg^2$。这是一个重要的努力，对未来的CMB实验，特别是那些旨在检测原始重力波签名的CMB偏振角功率谱的偏振前景的特征。
英文摘要：
The COsmic Foreground Explorer (COFE) is a balloon-borne microwave polarime- ter designed to measure the low-frequency and low-l characteristics of dominant diffuse polarized foregrounds. Short duration balloon flights from the Northern and Southern Hemispheres will allow the telescope to cover up to 80% of the sky with an expected sensitivity per pixel better than 100 $μK / deg^2$ from 10 GHz to 20 GHz. This is an important effort toward characterizing the polarized foregrounds for future CMB experiments, in particular the ones that aim to detect primordial gravity wave signatures in the CMB polarization angular power spectrum.
