The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the scientific goals of the experiment, motivate the design, and forecast its performance. SO will measure the temperature and polarization anisotropy of the cosmic microwave background in six frequency bands: 27, 39, 93, 145, 225 and 280 GHz. The initial configuration of SO will have three small-aperture 0.5-m telescopes (SATs) and one large-aperture 6-m telescope (LAT), with a total of 60,000 cryogenic bolometers. Our key science goals are to characterize the primordial perturbations, measure the number of relativistic species and the mass of neutrinos, test for deviations from a cosmological constant, improve our understanding of galaxy evolution, and constrain the duration of reionization. The SATs will target the largest angular scales observable from Chile, mapping ~10% of the sky to a white noise level of 2 $μ$K-arcmin in combined 93 and 145 GHz bands, to measure the primordial tensor-to-scalar ratio, $r$, at a target level of $σ(r)=0.003$. The LAT will map ~40% of the sky at arcminute angular resolution to an expected white noise level of 6 $μ$K-arcmin in combined 93 and 145 GHz bands, overlapping with the majority of the LSST sky region and partially with DESI. With up to an order of magnitude lower polarization noise than maps from the Planck satellite, the high-resolution sky maps will constrain cosmological parameters derived from the damping tail, gravitational lensing of the microwave background, the primordial bispectrum, and the thermal and kinematic Sunyaev-Zel'dovich effects, and will aid in delensing the large-angle polarization signal to measure the tensor-to-scalar ratio. The survey will also provide a legacy catalog of 16,000 galaxy clusters and more than 20,000 extragalactic sources.

The Physical Origin of Dark Energy Constraints from Rubin Observatory and CMB-S4 Lensing Tomography
我们试图澄清的起源约束的暗能量状态方程参数的CMB透镜层析，即结合星系团簇和星系的互相关与CMB透镜在一些红移箱。特别地，我们考虑了两点关联函数，它可以由星系位置表和来自Vera C的光度红移构成。Rubin Observatory Legacy Survey of Space and Time（LSST）和CMB Lensing Map来自CMB-S4实验。我们专注于分析理解的约束的起源。这些数据中的暗能量信息来自于三个主要关系的影响：距离作为红移的函数（几何），功率谱的振幅作为红移的函数（增长），以及功率谱作为波数的函数（形状）。我们发现，几何形状和生长的影响起着重要的作用，部分相互抵消，而形状的影响是不重要的。我们还表明，暗能量任务组（DETF）的品质因数（FoM）的预测相结合的LSST星系和CMB-S4透镜的预测宇宙剪切的情况下的CMB透镜图，从而提供了一个重要的独立检查。与单独使用LSST星系的预测相比，结合CMB透镜和LSST聚类信息（连同主CMB光谱），在系统性完全受控的乐观情况下，FoM大约增加了3-4倍。我们警告说，实现这些预测可能需要对高阶偏置，光度红移不确定性进行全面分析，并严格控制其他系统限制，这些都超出了这项工作的范围，其主要目的是阐明约束的物理起源。
