论文摘要
年轻的核心溢出型超新星（YSNE）是高能中微子和伽马射线的工厂，因为电击加速质子在密集的室内培养基中与质子有效相互作用。我们探索了IIIN，II-P，IIB/II-L和IB/C的YSNE的二级颗粒的检测前景。发现IIN YSNE型会产生最大的中微子和伽马射线通量，其次是II-P YSNE。 Fermi-Lat和Cherenkov望远镜阵列（IceCube-gen2）有可能检测到$ 10 $ 〜MPC（$ 4 $ 〜MPC）的IIN YSNE类型，其余的YSNE类型可检测到靠近地球。我们还发现，Ysne可能会占主导地位的中微子背景，尤其是在$ 10 $ 〜TEV和$ 10^3 $ 〜TEV之间，而它们并不构成Fermi-Lat观察到的各向同性伽马射线背景的主要组成部分。同时，ICECUBE高能量起始事件和费米LAT数据已经使我们可以排除YSNE模型参数空间的很大一部分，否则从这些瞬变的多波长电磁观测中推断出来。
Young core-collapse supernovae (YSNe) are factories of high-energy neutrinos and gamma-rays as the shock accelerated protons efficiently interact with the protons in the dense circumstellar medium. We explore the detection prospects of secondary particles from YSNe of Type IIn, II-P, IIb/II-L, and Ib/c. Type IIn YSNe are found to produce the largest flux of neutrinos and gamma-rays, followed by II-P YSNe. Fermi-LAT and the Cherenkov Telescope Array (IceCube-Gen2) have the potential to detect Type IIn YSNe up to $10$~Mpc ($4$~Mpc), with the remaining YSNe Types being detectable closer to Earth. We also find that YSNe may dominate the diffuse neutrino background, especially between $10$~TeV and $10^3$~TeV, while they do not constitute a dominant component to the isotropic gamma-ray background observed by Fermi-LAT. At the same time, the IceCube high-energy starting events and Fermi-LAT data already allow us to exclude a large fraction of the model parameter space of YSNe otherwise inferred from multi-wavelength electromagnetic observations of these transients.
