摘要:

冰立方实验最近报告了对高能宇宙中微子的首次观测。它们的起源仍然不明。在本文中,我们调查的可能性,它们起源于活动星系。我们表明,强子相互作用(PP)在一般不太强大,更频繁,FR-I射电星系的候选源类能够容纳的观察,而更强大,更频繁,类FR-II射电星系有太低的列深度来解释的信号之一。

英文摘要:

The IceCube experiment has recently reported the first observation of high-energy cosmic neutrinos. Their origin is still unknown. In this paper, we investigate the possibility that they originate in active galaxies. We show that hadronic interactions (pp) in the generally less powerful, more frequent, FR-I radio galaxies are one of the candidate source classes being able to accommodate the observation while the more powerful, less frequent, class of FR-II radio galaxies has too low of a column depths to explain the signal.
