Abstract

Over the past ten years, several breakthroughs have been made in multi-messenger astronomy. Thanks to the IceCube Neutrino Observatory, the detection of astrophysical neutrinos was proved to be practical. However, due to the limited statistics and field of view, only a few sources have been associated with IceCube neutrinos, making new and larger neutrino telescopes necessary. We propose the NEutrino Observatory in the Nanhai (NEON), located in the South China Sea to be complementary for the global neutrino detectors. This proposal describes the design and layout of the array and reports on comprehensive simulations conducted to assess its performance. The NEON project, with a volume of 10 km

^{3}

, achieves an angular resolution of 0.1 ° at 100 TeV. With 10 years of operation, the project’s 5

σ

sensitivity is estimated as

E^{2} Φ \sim 3 \times 1 0^{- 10}

GeV cm⁻² s⁻¹ for a source spectrum index of -2. We found that the variation in depth from 1700 to 3500 meters does not significantly influence the sensitivity to steady sources.

拟建的南海深海中微子观测站

在过去的十年里，多信使天文学取得了一些突破。多亏了冰立方中微子天文台，天体物理中微子的探测被证明是可行的。然而，由于有限的统计数据和视野，只有少数来源与冰立方中微子有关，这使得新的和更大的中微子望远镜成为必要。我们建议在南海建立中微子天文台（NEON），作为全球中微子探测器的补充。本提案描述了阵列的设计和布局，并报告了进行综合模拟以评估其性能。NEON项目的体积为10 km3，在100 TeV下实现了0.1°的角分辨率。经过10年的运行，该项目的5σ灵敏度估计为E2Φ ~ 3×10−10 GeV cm−2 s−1，源光谱指数为-2。我们发现1700 ~ 3500米的深度变化对稳定源的灵敏度没有显著影响。
