Multi-messenger astronomy, using electromagnetic radiation (radio waves, visible light, X-rays, gamma rays), neutrinos, and gravitational waves, is providing unprecedented observations of extreme astrophysical environments, such as supernovae and merging neutron stars. The diverse range of nuclear and astrophysics that needs to be synthesized to answer open questions about the universe cannot be obtained by a single country. The International Research Network for Nuclear Astrophysics (IReNA) project connects research networks and capabilities across disciplines and geographic boundaries to advance understanding of the origin of chemical elements and the nature of dense nuclear matter. This network of networks links the U.S. Joint Institute for Nuclear Astrophysics Center for the Evolution of Elements (JINA-CEE) with similar undertakings in Europe (ChETEC), Japan (UKAKUREN), Germany (EMMI and The Milky Way system), and the international NuGRID network. IReNA creates the communication channels and collaborative structures needed for rapid scientific response to new multi-messenger discoveries. Exchange programs, innovative workshops, and retreats will foster network communication and training of the next generation of scientists. Multi-messenger astronomical observation of supernovae and merging neutron stars is leading to a better understanding of and further questions on the origin of chemical elements and the physics of dense nuclear matter. For multi-messenger data to become true windows on the universe, an unprecedented amount of astrophysics and nuclear physics associated with the various messengers and their interactions must be understood. The IReNA project brings together U.S. and international networks with complementary capabilities to exchange and synthesize data, models, theory, and expertise in astrophysics and nuclear physics. The research goals are to advance our understanding of element formation in stars, stellar explosions, and neutron star mergers through new nuclear physics experiments, nuclear theory, advanced computational modeling, and new observations of the distribution of elements in stars across our Galaxy. The expanded collaborations will enable synthesis and exchange of data sets across international communities and expand capabilities far beyond what would be possible by any individual network.The Accelerating Research through International Network-to-Network Collaborations (AccelNet) program is designed to accelerate the process of scientific discovery and prepare the next generation of U.S. researchers for multiteam international collaborations. The AccelNet program supports strategic linkages among U.S. research networks and complementary networks abroad that will leverage research and educational resources to tackle grand scientific challenges that require significant coordinated international efforts.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.

利用电磁辐射（无线电波、可见光、X射线、伽马射线）、中微子和引力波的多信使天文学正在提供对极端天体物理环境（如超新星和合并中子星）的前所未有的观测。为了回答关于宇宙的公开问题，需要综合各种各样的核物理学和天体物理学知识，而这些知识不可能由一个国家获得。 国际核天体物理研究网络（IReNA）项目将跨学科和地理边界的研究网络和能力连接起来，以促进对化学元素起源和致密核物质性质的理解。 该网络将美国联合研究所的元素演化核天体物理中心（JINA-CEE）与欧洲（ChETEC）、日本（UKAKUREN）、德国（EMMI和银河系）和国际NuGRID网络的类似项目联系起来。 IReNA创建了快速科学响应新的多信使发现所需的通信渠道和协作结构。 交流项目、创新研讨会和务虚会将促进下一代科学家的网络交流和培训。 对超新星和合并中子星的多信使天文观测正在导致对化学元素的起源和致密核物质的物理学的更好理解和进一步的问题。为了使多信使数据成为真正的宇宙窗口，必须了解与各种信使及其相互作用相关的前所未有的天体物理学和核物理学。IReNA项目汇集了美国和国际网络，具有互补能力，可以交换和综合天体物理学和核物理学的数据，模型，理论和专业知识。研究目标是通过新的核物理实验，核理论，先进的计算模型和对银河系恒星中元素分布的新观测，促进我们对恒星中元素形成，恒星爆炸和中子星星合并的理解。 扩大的合作将使跨国际社区的数据集的合成和交换成为可能，并将能力扩展到远远超出任何单个网络的能力。通过国际网络到网络合作加速研究（Accelerating Research through International Network-to-Network Collaborations，简称CNET）计划旨在加速科学发现的进程，并为下一代美国研究人员进行多团队国际合作做好准备。 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。
