论文摘要

极端多理智的天体物理学（诗歌）的探测旨在准确观察到超高能量宇宙射线（UHECR）和宇宙中微子，从空间中具有灵敏度，对全天空的敏感性。诗歌将通过空气荧光观察到UHECR和UHE中微子的广泛空气阵雨（EAS）。此外，诗歌将观察到来自20 PEV以上的地球中微子引起的向上移动EAS的Cherenkov信号。诗歌航天器的设计旨在快速重新定位以跟进瞬态中微子来源并获得无与伦比的中微子通量敏感性。作为NASA天体物理学探测级任务，诗歌由两个相同的卫星组成，在525公里的高度轨道上飞行。每种诗歌乐器都包含广泛的视野（45 $^\ circ $）Schmidt望远镜，并具有超过6 m $^2 $的收集区域。每个望远镜的混合局灶性表面包括用于EAS荧光观测值的快速（1〜 $ $ $ S）近粉状摄像头和用于Cherenkov EAS观测值的超快（10〜NS）光学摄像头。在一个为期5年的任务中，诗歌将提供测量，以打开新的多通信窗口到宇宙中最有活力的事件，从而在这些原本无法访问的能量上研究新的天体物理学和粒子物理学。

The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to accurately observe ultra-high-energy cosmic rays (UHECRs) and cosmic neutrinos from space with sensitivity over the full celestial sky. POEMMA will observe the extensive air showers (EASs) from UHECRs and UHE neutrinos above 20 EeV via air fluorescence. Additionally, POEMMA will observe the Cherenkov signal from upward-moving EASs induced by Earth-interacting tau neutrinos above 20 PeV. The POEMMA spacecraft are designed to quickly re-orientate to follow up transient neutrino sources and obtain unparalleled neutrino flux sensitivity. Developed as a NASA Astrophysics Probe-class mission, POEMMA consists of two identical satellites flying in loose formation in 525 km altitude orbits. Each POEMMA instrument incorporates a wide field-of-view (45$^\circ$) Schmidt telescope with over 6 m$^2$ of collecting area. The hybrid focal surface of each telescope includes a fast (1~$μ$s) near-ultraviolet camera for EAS fluorescence observations and an ultrafast (10~ns) optical camera for Cherenkov EAS observations. In a 5-year mission, POEMMA will provide measurements that open new multi-messenger windows onto the most energetic events in the universe, enabling the study of new astrophysics and particle physics at these otherwise inaccessible energies.
