在ICECUBE实验中,通过分析(2010-2010-2017)的数据,在ICECUBE实验中发现了高能天体物理PEV中微子的证据。活性银河核(AGN)是宇宙中最突出的物体之一,被广泛推测为具有质子统治的超高能量(UHE)宇宙射线的发射器。基于标准的两步LLCD粒子加速度机理,能量的转化是从AGN的中央超质量黑洞(SMBH)旋转到高能质子的。质子可以加速至$ \ sim 0.1 $ eev Energies及以上,并且可能通过Plaausible Hadronic互动在能量范围内产生PEV中微子$ 1 $ - $ 10 $ 〜PEV。在理论上估计的经过修订的性交弥漫性muON中微子通量使用“依赖于光度的密度演化(LDDE)模型”模型的AGN光度函数(LF)与ICECUBE水平相一致,只要仅是iCecube水平,只有分数为6.56 \ $ 6.56 \%$ $ 6.56 \%的总玻璃仪(BL)的pev seactreme and agn seactr and agn iniz and and and and agn iniz iniz iniz iniz and and vate and vate and vate and vate and vate and and and and and and and and and and and and and。在具有LDDE建模的LF和Photon指数分布的$λ$ 〜CDM宇宙学框架中,总BL的$ 5.18 \%$足以为Icecube Neutminos提供动力。
Evidence for high-energy astrophysical PeV neutrinos has been found in the IceCube experiment from an analysis with a 7.5 year (2010 - 2017) data. Active galactic nuclei (AGN) are among the most prominent objects in the universe, and are widely speculated to be emitters of ultra-high-energy (UHE) cosmic rays with proton domination. Based on the standard two-step LLCD mechanism of particle acceleration, a transformation of energy occurs from AGN's central super-massive black hole (SMBH) rotation to high-energy protons. Protons can be accelerated up to $\sim 0.1$ EeV energies and above, and might generate PeV neutrinos in the energy range $1$--$10$~ PeV through plausible hadronic interactions. The theoretically estimated revised extragalactic diffuse muon neutrino flux employing the "luminosity-dependent density evolution (LDDE)" model for the AGN luminosity function (LF) is found consistent with the IceCube level if only a fraction, $6.56\%$ of the total bolometric luminosity (BL) of AGN is being realizable to power the PeV neutrinos. In the $Λ$~CDM cosmological framework with the LDDE modeled LF and photon index distribution, about $5.18\%$ of the total BL is enough to power the IceCube neutrinos.
