Non-Gaussiantity in the Cosmic Microwave Background

该项目将与西蒙斯天文台（SO）合作，使用MODAL管道约束非高斯性。这将涉及几个阶段：首先，必须对代码进行升级，并在更高分辨率的SO数据下进行验证。然后，代码将被扩展，以涵盖更大范围的原始模型，并测量几个需要解释的晚时间效应。代码还需要为公开发布做好准备。除了以SO为重点的工作之外，我们希望将我们团队中的类似项目连接到大尺度结构，特别是星系与透镜重建的相互关联，以及有效地计算暴胀模型的非高斯特征的工作。

The project will involve working within the Simons Observatory (SO) collaboration to constrain non-Gaussianity using the MODAL pipeline. This will involve several phases: First the code will have to be upgraded and validated at the higher resolution of SO data. The code will then be expanded to cover a larger range of primordial models and to measure several late time effects which will need to be accounted for. The code will also need to be prepared for public release. In addition to the SO focused work, we expect to connect to similar projects in our group in both Large Scale Structure, specifically cross correlations of Galaxy's with lensing reconstructions, and work to efficiently calculate non-Gaussian signatures from inflationary models.
