论文摘要
即将到来的中微子望远镜可能会在未来10 - 20年内发现超高能量（UHE）宇宙中微子，能量超过100 PEV。找到它们的来源将确定宇宙射线相互作用的保证位置，其起源是未知的。我们通过寻找从相似方向到达的UHE中微子的多重组来搜索来源。我们的预测是最先进的，适合IceCube-gen2中的中微子无线电检测。他们解释了检测器能量和角度响应，以及关键但不确定的背景。 $ -45^\ circ $ to $ 0^\ circ $的拒绝源将是最容易发现的。即使在10年内发现一个稳态来源也意味着该来源的中微子光度至少大于$ 10^{43} $ erg/s（取决于源红移的演化）。发现没有瞬态来源会不利于瞬态来源比$ 10^{53} $ erg更明亮。我们的结果旨在告知即将到来的探测器的设计。
Upcoming neutrino telescopes may discover ultra-high-energy (UHE) cosmic neutrinos, with energies beyond 100 PeV, in the next 10-20 years. Finding their sources would identify guaranteed sites of interaction of UHE cosmic rays, whose origin is unknown. We search for sources by looking for multiplets of UHE neutrinos arriving from similar directions. Our forecasts are state-of-the-art, geared at neutrino radio-detection in IceCube-Gen2. They account for detector energy and angular response, and for critical, but uncertain backgrounds. Sources at declination of $-45^\circ$ to $0^\circ$ will be easiest to discover. Discovering even one steady-state source in 10 years would imply that the source has an UHE neutrino luminosity at least larger than about $10^{43}$ erg/s (depending on the source redshift evolution). Discovering no transient source would disfavor transient sources brighter than $10^{53}$ erg as dominant. Our results aim to inform the design of upcoming detectors.
