This award will support a study of the effects of baryonic matter on cosmological constraints on dark energy as derived from future weak lensing surveys. Large-scale numerical simulations of cosmological structure formation will be performed that treat the physics of baryons in detail. The information garnered from the simulation programs will be used to develop the techniques that will be needed to make optimal use of future photometric surveys to constrain the properties of dark energy and the process of galaxy formation.Broader impacts of this work include research training for a graduate student. All simulation data, processed data products, analysis tools and software developed as part of this project will be made available freely to the scientific community. Simulation visualizations and results will be discussed as part of regular public lecture series at the Allegheny Observatory and will be incorporated into the Carnegie Science Center Girls Science & Math Project to build interest in astrophysical sciences.

该奖项将支持一项研究重子物质对暗能量宇宙学约束的影响，这项研究将从未来的弱透镜观测中得出。宇宙结构形成的大规模数值模拟将进行详细处理重子物理。从模拟程序中获得的信息将用于开发所需的技术，以最佳地利用未来的光度调查来约束暗能量的特性和星系形成过程。这项工作更广泛的影响包括对研究生的研究训练。作为该项目的一部分，所有模拟数据、处理数据产品、分析工具和软件将免费提供给科学界。模拟可视化和结果将作为阿勒格尼天文台定期公开讲座系列的一部分进行讨论，并将被纳入卡内基科学中心女孩科学与数学项目，以培养对天体物理科学的兴趣。
