Astrophysical phenomena, and particularly the most energetic, emit a range of particles from photons to neutrinos and cosmic rays. They may also produce gravitational radiation. These "messengers" carry details of the energetics and physical conditions in these sources. The Astrophysical Multimessenger Observatory Network (AMON) aims to discover new particle astrophysics phenomena by merging the world's leading multimessenger observatories into a single data system for the first time. The facilities to be linked by AMON observe high-energy neutrinos (the IceCube and ANTARES Neutrino Observatories), the strongly-interacting nuclei observed as cosmic rays (the Pierre Auger Cosmic Ray Observatory), and in future phases, the oscillations in the fabric of space-time manifested as gravitational waves (the Advanced LIGO and VIRGO gravitational-wave detectors). These are complemented by current and next-generation gamma-ray facilities, including the Swift and Fermi satellites and the HAWC gamma-ray observatory. Over the three year award period, the PIs will construct a prototype AMON network with the scientific goal of discovering the first jointly-emitting gamma-ray and high-energy neutrino sources. In conjunction with the AMON project, the PIs will also initiate and run "AstroTxt," an applied educational experience that will involve central Pennsylvania middle and high school students directly in real-time AMON operations. AMON will assemble the first terabyte-scale multimessenger database and develop tools for data exchange and real-time correlation analysis, establishing a superior level of interoperability. This new and transparent sharing of data promises significant scientific advances: Data from individual facilities that in isolation cannot be interpreted as the detection of an astrophysical source, may achieve a higher level of significance in a joint coincident analysis of data from multiple participating observatories. Each candidate astrophysical signal will be packaged as an electronic AMON Alert and distributed to a network of follow-up facilities for counterpart searches and characterization. Identification of an x-ray, optical, or radio counterpart will serve to confirm the astrophysical nature of an event and enable a broad range of detailed studies, including distance or redshift measurement, using traditional astronomical techniques.

天体物理现象，尤其是最有能力的现象，散发出从光子到中微子和宇宙射线的一系列颗粒。 它们也可能产生重力辐射。 这些“使者”提供了这些来源中能量和物理状况的细节。 天体物理多通电子天文台网络（AMON）旨在通过首次将世界领先的多中音仪观测器合并到单个数据系统中来发现新的粒子天体物理现象。 The facilities to be linked by AMON observe high-energy neutrinos (the IceCube and ANTARES Neutrino Observatories), the strongly-interacting nuclei observed as cosmic rays (the Pierre Auger Cosmic Ray Observatory), and in future phases, the oscillations in the fabric of space-time manifested as gravitational waves (the Advanced LIGO and VIRGO gravitational-wave detectors).这些与当前和下一代伽马射线设施相辅相成，包括Swift和Fermi卫星以及HAWC Gamma-ray天文台。 在三年奖励期内，PI将建立一个原型Amon网络，其科学目标是发现第一个共同发射的伽马射线和高能量中微子来源。 与Amon项目一起，PIS还将启动和运行“ Astrotxt”，这是一种应用的教育经验，将直接在实时AMON运营中涉及宾夕法尼亚州中部中学和高中生。 Amon将组装第一个Terabyte尺度的多通用器数据库，并开发用于数据交换和实时相关分析的工具，从而建立较高的互操作性水平。 数据的新数据共享有望取得重大的科学进步：来自单个设施的数据不能孤立地解释为对天体物理学来源的检测，在对多个参与观察员的数据的联合重合分析中可能会获得更高的显着性。 每个候选天体物理信号将被包装为电子AMON警报，并分布在后续设施网络中，以进行对应的搜索和表征。 X射线，光学或无线电对应物的识别将有助于确认事件的天体物理性质，并使用传统的天文学技术实现广泛的详细研究，包括距离或红移测量。
