冰立方实验最近报告了对高能宇宙中微子的首次观测。它们的起源仍然未知。在本文中,我们研究了它们起源于活动星系的可能性。我们发现强子相互作用(pp)在通常不太强大、更频繁的FR-I射电星系中是能够容纳观测的候选源类之一,而更强大、更不频繁的FR-II射电星系的柱深度太低,无法解释信号。
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.
