摘要:

高能中微子IC-170922 A在空间(在误差区域内)和时间耀斑活动与耀变体TXS 0506+056的相关性的检测允许这些物体被认为是中微子的祖先来源。除此之外,没有再报告发现这类情况。IceCube探测到的其他一些中微子显示出与其他费米LAT探测源的空间相关性(在误差区域内)。然而,这些天体并没有像TXS 0506+056那样显示出耀斑活动。假设p $γ$相互作用是一种轻强子的情形,本文描述了费米伽玛射线空间望远镜大面积望远镜(4LAC)源探测到的第四类活动星系核(AGN)中的一些天体的超对称电子自旋,这些天体与IceCube探测到的中微子具有空间相关性。此外,我们估计相应的中微子通量对应这些来源。

英文摘要:

The detection of the high-energy neutrino IC-170922A in spatial (within the error region) and temporal flare activity correlation with the blazar TXS 0506+056 allowed these objects to be considered as progenitor sources of neutrinos. Besides this, no more detection of this kind was reported. Some other neutrinos detected by IceCube show a spatial correlation (within the error region) from other Fermi-LAT detected sources. However, these objects did not show a flare activity like TXS 0506+056. Assuming a lepto-hadronic scenario through p$γ$ interactions, this work describes the SED in some objects from the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi Gamma-ray Space Telescope Large Area Telescope (4LAC) sources, which are in spatial correlation with neutrinos detected by IceCube. Additionally, we estimate the corresponding neutrino flux counterpart from these sources.
