Cosmology from the Cosmic Microwave Background with the Simons Observatory

西蒙斯天文台是新一代宇宙微波背景(CMB)实验，目前正在建造中，准备部署在智利阿塔卡马沙漠。这个项目将有两条线索。第一项工作将侧重于与这一多国项目相关的计算和分析基础设施方面的工作，可能包括分析原始数据时间流、测量仪器的光学性质以及规划观测活动。第二流将强调对实验的最终宇宙学结果的预测：在现实仪器误差和天体物理污染的影响下，可以检测到对当前宇宙学模型的哪些扩展，以及精度如何。

The Simons Observatory is a next-generation Cosmic Microwave Background (CMB) experiment currently being built for deployment in the Atacama Desert, Chile. This project will have two strands. The first will emphasise work on the computing and analysis infrastructure relevant to this multi-national project, possibly including analysis of the raw data time-stream, measurement of the optical properties of the instruments, and planning the observational campaign. The second stream will emphasise predictions for the final cosmological results from the experiment: what extensions to the current cosmological model can be detected, and with which precision, under the influence of realistic instrumental errors and astrophysical contamination.
