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.

西蒙斯天文台是下一代宇宙微波背景（CMB）实验，目前正在智利阿塔卡马沙漠进行部署。该项目将有两个链。第一个将强调与该跨国项目相关的计算和分析基础架构的工作，可能包括对原始数据时间流的分析，仪器的光学特性的测量以及计划观测活动。第二个流将强调实验中最终宇宙学结果的预测：可以检测到当前宇宙学模型的扩展，以及在现实的仪器误差和天体物理污染的影响下的精度。
