The recent detection of X-rays from hot spots on the surface of rotating neutron stars and the observation of the gravitational waves emitted when neutron stars collide hold the promise of revealing the mysteries of nuclear astrophysical phenomena in a previously inaccessible regime. Meanwhile, in the laboratory, heavy-ion collision experiments, akin to miniature neutron star mergers, can reveal complementary information about the properties of matter at extreme temperatures and densities. A core group of research teams at the University of Illinois Urbana-Champaign, the National Center for Supercomputing Applications, the University of Houston, Kent State University, and several other auxiliary institutions are creating a new cyberinfrastructure that can rapidly and efficiently describe nuclear matter across vastly different densities and temperatures. This open cyberinfrastructure allows users to understand the nature of the building blocks of matter through comparisons with data from NASA’s Neutron Star Interior Composition Explorer, the National Science Foundation’s Laser Interferometer Gravitational-wave Observatory, the Department of Energy’s fixed target Solenoid Tracker at the Relativistic Heavy Ion Collider, and other international facilities. The project provides outreach to the community through an online science portal that makes high-end computations more approachable for end users with additional tutorials, extended showcases, and detailed documentation.The research plan creates a cyberinfrastructure, MUSES (Modular Unified Solver of the EoS), that provides various scientific communities with novel tools to help answer critical interdisciplinary questions in nuclear astrophysics, gravitational wave astrophysics, and heavy-ion experiments. The investigators are creating modern, efficient and parallelizable code to generate equation-of-state modules in different regimes of density, pressure, and temperature in either 2, 3, or 4 dimensions. These modules are then integrated into a single, standardized global calculational engine that allows the fast generation of equations-of-state across the entire phase diagram of quantum chromodynamics — the fundamental theory of strong interactions. The project creates a web interface with a collection of application programming interfaces that allows external users to run the MUSES cyberinfrastructure remotely and deploy it in high-performance computing clusters. In particular, the plug-and-play operability of MUSES allows external users to select parameters in the equation-of-state package to run a given set of modules and generate a global EoS with a chosen set of observable byproducts. This project advances the goals of the Division of Physics and the Office of Advanced Cyberinfrastructure of the National Science Foundation.This award by the Office of Advanced Cyberinfrastructure is jointly supported by the Windows on the Universe NSF Big Idea program, the Physics at the Information Frontier (PIF) program in the Division of Physics (PHY), and the Division of Astronomical Sciences (AST).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

最近对旋转中子星表面热点X射线的探测和对中子星碰撞时发出的引力波的观测，有望揭示以前无法理解的核天体物理现象的奥秘。与此同时，在实验室中，类似于微型中子星星合并的重离子碰撞实验可以揭示关于极端温度和密度下物质性质的补充信息。伊利诺伊大学厄巴纳-香槟分校、国家超级计算应用中心、休斯顿大学、肯特州立大学和其他几个辅助机构的核心研究团队正在创建一个新的网络基础设施，可以快速有效地描述不同密度和温度的核物质。这种开放的网络基础设施使用户能够通过与美国宇航局的中子星星内部成分探测器、国家科学基金会的激光干涉仪引力波天文台、能源部在相对论重离子对撞机上的固定目标螺线管跟踪器以及其他国际设施的数据进行比较，了解物质组成单元的性质。该项目通过一个在线科学门户网站向社区提供外展服务，通过额外的教程、扩展的展示和详细的文档，使高端计算更容易为最终用户所用。（EoS的模块化统一求解器），为各种科学团体提供了新的工具，以帮助回答核天体物理学中的关键跨学科问题，引力波天体物理学和重离子实验。研究人员正在创建现代，高效和可并行化的代码，以在2维，3维或4维的密度，压力和温度的不同区域中生成状态方程模块。然后，这些模块被集成到一个单一的、标准化的全局计算引擎中，该引擎允许在强相互作用的基础理论量子色动力学的整个相图中快速生成状态方程。该项目创建了一个包含一系列应用程序编程接口的Web界面，允许外部用户远程运行Muses网络基础设施，并将其部署在高性能计算集群中。特别是，Muses的即插即用可操作性允许外部用户选择状态方程包中的参数，以运行给定的一组模块，并生成具有选定的一组可观察副产品的全局EoS。该项目推进了物理部和国家科学基金会高级网络基础设施办公室的目标。高级网络基础设施办公室的这一奖项由NSF大创意计划的Windows on the Universe，物理部（PHY）的信息前沿物理（PIF）计划，该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
