Lisa Johanna Schumacher, Foteini Oikonomou

AI总结:

本研究提出整合全球现有及未来中微子观测站的PLEnuM方法,估算了其对耀变体、GRB等瞬变中微子源的探测能力提升,并验证了其可提高全天甚高能中微子的实时探测率。

摘要:

IceCube在TeV-PeV能段发现高能天体物理中微子,标志着中微子天文学的开端,目前对其来源的搜寻仍在继续。IceCube已确定两个有潜力的候选源:1 TeV-10 TeV能段的NGC 1068,以及0.1-1 PeV能段的TXS 0506+056。这两个源都有伽马射线对应体,但中微子与伽马射线的额外时间信息对识别TXS 0506+056至关重要。行星际中微子监测(Planetary Neutrino Monitoring,PLEnuM)概念是一种整合所有现有及未来中微子观测站曝光量的方法,这些观测站包括北半球的KM3NeT、Baikal-GVD、P-ONE,以及南半球的IceCube-Gen2。利用PLEnuM方法,我们估算了未来中微子观测站投入运行后,对耀变体、伽马射线暴(GRB)等瞬变候选源的探测能力提升幅度。此外,我们还展示了PLEnuM的组合瞬时视场如何提升全天范围内稀有甚高能中微子的实时探测率。

英文摘要:

The discovery of high-energy astrophysical neutrinos in the TeV-PeV range by IceCube marked the start of neutrino astronomy, and the search for their sources continues. Two promising source candidates have been identified by IceCube: NGC 1068 in the 1 TeV-10 TeV range and TXS 0506+056 in the 0.1-1 PeV range. Both sources have gamma-ray counterparts, but additional time information of both neutrinos and gamma rays were essential for the identification of TXS 0506+056. The Planetary Neutrino Monitoring (PLEnuM) concept is an approach for combining the exposures of all current and future neutrino observatories - such as KM3NeT, Baikal-GVD, P-ONE in the Northern Hemisphere, and IceCube-Gen2 in the Southern Hemisphere. Using this PLEnuM approach, we estimate how the detection capability for transient sources candidates like blazars and GRBs improves once the future neutrino observatories come online. In addition, we present how the combined, instantaneous field of view of PLEnuM improves the real-time detection rate of rare, very-high-energy neutrinos across the entire sky.
