A Unified Study of Dark Energy and Galaxy Formation

这一奖项将支持一项关于重子物质对宇宙学限制暗能量的影响的研究，这项研究来自未来的弱透镜调查。将进行大规模的宇宙结构形成的数值模拟，详细讨论重子的物理问题。从模拟程序中获得的信息将被用来开发所需的技术，以最大限度地利用未来的光度测量来限制暗能量的性质和星系形成的过程。这项工作的广泛影响包括研究生的研究培训。作为该项目的一部分而开发的所有模拟数据、经过处理的数据产品、分析工具和软件将免费提供给科学界。模拟的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和数学项目，以培养人们对天体物理科学的兴趣。

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.
