This award establishes a multi-institutional and international collaborative Multi-messenger Plasma Physics Center (MPPC) focused on studying fundamental plasma processes with the goal of modeling sources of astrophysical signals. Recent discoveries of gravitational waves from merging black holes and neutron stars and the detections of energetic neutrinos and ultra-high energy cosmic rays herald the rise of multi-messenger astronomy (MMA) aiming to observe the sky not only through light, but also through gravitational waves and energetic particles. Interpretation of MMA signals, however, crucially depends on our ability to understand, predict, and model the electromagnetic counterparts of multi-messenger sources. In most theories of these sources, the light is coming from a relativistic plasma that experiences very strong gravitational, magnetic and radiation fields. How plasmas produce the observable radiation under these conditions challenges our understanding of plasma physics. MPPC will study the fundamental processes in relativistic plasmas that lead to the observable emission from multimessenger sources, and thus addresses goals of NSF's "Windows on the Universe: The Era of Multi-Messenger Astrophysics". The investigators will mentor summer research for undergraduate and high school students and will increase awareness of plasma astrophysics through introductory lectures at minority-serving undergraduate institutions and through public outreach. The MPPC research will be concentrated in three areas: 1) basic physics of relativistic pair plasmas near compact objects, including radiative relativistic reconnection, pair creation, and interaction of strong waves with plasmas; 2) multi-scale modeling of compact objects, including the development of global models of merging neutron star magnetospheres, magnetar outbursts, black hole accretion disk flares, and particle acceleration in jets; 3) the physics of transport of cosmic rays in our galaxy, including streaming instabilities and interactions of cosmic rays with turbulence. The collaboration will develop models that will be used to predict electromagnetic precursors of neutron star mergers, constrain the sites of acceleration of ultra-high energy cosmic rays, and improve cosmic ray transport models for galactic wind driving. The Center will also provide scientific leadership in designing laboratory experiments for studying relativistic astrophysical plasmas with ultra-intense lasers. The Center includes four US nodes - Princeton University, Columbia University, University of Maryland, and Washington University in St. Louis, - and will have an international collaborative component with the participation of Max Planck Society institutes.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.

该奖项建立了一个多机构和国际协作的多门会等离子物理中心（MPPC），旨在研究基本血浆过程，目的是建模天体物理信号的来源。 重力波从合并黑洞和中子星以及能量中微子的检测和超高的能量宇宙射线的发现最近发现的，旨在通过光观察到天空，不仅通过光线，而且通过引力和能量颗粒观察到天空。 但是，MMA信号的解释至关重要地取决于我们理解，预测和建模多通信源的电磁对应物的能力。在这些来源的大多数理论中，光来自相对论的等离子体，该等离子体体验非常强的引力，磁场和辐射场。在这些条件下，等离子体如何产生可观察到的辐射挑战了我们对血浆物理学的理解。 MPPC将研究相对论等离子体中的基本过程，从而导致多通电源可观察到的发射，从而解决NSF“宇宙中的窗口：多通信器天体物理学时代”的目标。调查人员将指导本科生和高中生的夏季研究，并通过在少数派服务本科机构的入门讲座以及通过公共宣传来提高对等离子体天体物理学的认识。 MPPC的研究将集中在三个领域：1）相对论对等离子体的基本物理，包括紧凑的物体，包括辐射相对论重新连接，成对创建以及强波与等离子体的相互作用； 2）紧凑型物体的多尺度建模，包括合并中子星磁层合并的全局模型，磁铁爆发，黑洞积聚磁盘的耀斑和喷气机中的颗粒加速度； 3）我们银河系中宇宙射线的运输物理学，包括流式不稳定性和湍流的相互作用。该协作将开发模型，这些模型将用于预测中子星合并的电磁前体，限制超高能宇宙射线加速的位置，并改善用于银河风驱动的宇宙射线传输模型。该中心还将在设计实验室实验方面提供科学领导力，以使用超注射激光研究相对论的天体物理等离子体。该中心包括四个美国节点 - 普林斯顿大学，哥伦比亚大学，马里兰大学和圣路易斯的华盛顿大学，并将在Max Planck Society Institutes的参与下建立国际合作组成部分。这项奖项反映了NSF的法定任务，并通过该基金会的知识绩效和广泛的criperia criperia criperia criperia criperia cripteria revalluation the NSF的法定任务。
