项目摘要

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.

当中子星星碰撞时，在旋转中性恒星表面的热点的X射线发现最近发现的引力波的观察有望在以前无法接近的状态下揭示核天体物理现象的奥秘。同时，在实验室中，重型离子碰撞实验类似于微型中性星星合并，可以揭示有关物质在极端温度和密度下的特性的完整信息。伊利诺伊大学Urbana-Champaign，国家超级计算应用中心，休斯顿大学，肯特州立大学以及其他几个辅助机构的核心研究团队正在创建一个新的CyberinFrastructure，可以在广泛不同的不同密度和温度下快速有效地描述一个新的CyberinFrastruct。这种开放的网络基础设施使用户可以通过与NASA的NEDRON STAR Star Interior Composition Explorer的数据进行比较，该数据是国家科学基金会的激光干涉仪重力波电波观测站，Energy Sociader基金会的激光干涉仪重力波动台，能源部的固定目标螺旋体跟踪器，相对性重型离子Collider和其他国际设施。 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实验。研究人员正在创建现代，高效和可行的代码，以在2、3或4个维度中以不同密度，压力和温度的不同状态生成状态模块。然后将这些模块集成到单个标准化的全局计算引擎中，该发动机允许在量子铬动力学的整个阶段图中快速生成状态方程，这是强相互作用的基本理论。该项目使用应用程序编程接口的集合创建Web界面，该界面允许外部用户远程运行Cyberinfrastructure，并将其部署在高性能计算群集中。特别是，缪斯女神的插件操作使外部用户可以在状态软件包中选择参数来运行一组给定的模块，并使用选择的一组可观察的副产品生成全局EO。该项目推动了国家科学基金会的物理部门和高级网络基础设施办公室的目标。该奖项由宇宙NSF Big Ideas Program的高级网络基础设施办公室共同支持，该计划是Information Frontier（PIF）的物理学（PIF）裁决（PHY）和Scipory of Sciess（Ast）。使用基金会的知识分子优点和更广泛的审查标准，被认为值得通过评估来支持。
