开展亚角分分辨率全天毫米波巡测的理由
The case for an all-sky millimetre survey at sub-arcminute resolution
AI总结:
本文论证为15米天线建造大型焦平面 KID 相机,以在五年内完成北半球亚角分分辨率、毫央斯基灵敏度毫米波巡测,并阐述其科学目标与实施挑战。
摘要:
目前有若干利用毫米波观测设备巡测天空的新项目,其中规模最大的是位于南半球的 Simons Observatory 和 CMB-S4。NIKA2 合作组已经积累了足够的知识,能够为一台15米天线构建大型焦平面 KID 相机。这将使人们能够在五年内以亚角分分辨率和毫央斯基点源灵敏度覆盖整个北半球。我们描述了这一项目的主要科学驱动力:SZ 天空、高红移毫米波宇宙,以及银河系和近邻星系中的星际介质。我们还简要说明了主要困难,包括科学、组织、技术和财务方面。
英文摘要:
There are several new projects to survey the sky with millimetre eyes, the biggest being Simons Observatory and CMB-S4, in the Southern Hemisphere. The NIKA2 collaboration has acquired sufficient knowledge to build a large focal plane KID camera for a 15~m antenna. This would allow covering the whole Northern Hemisphere in five years at subarcminute resolution and with milliJansky point-source sensitivity. We describe the main scientific drivers for such a project: the SZ sky, the high-redshift millimetre Universe and the interstellar medium in our Galaxy and the nearby galaxies. We also show briefly the main difficulties (scientific, organisational, technical and financial).
