局域磁星的PeV中微子

PeV neutrinos from local magnetars

Rajat K. Dey

摘要:

本文估计了磁星极帽的PeV中微子通量,假设离子/质子被注入,并在这些区域加速,并与辐射背景相互作用。本研究考虑了光子分裂机制的影响,应该修改的辐射背景,并提高在PeV能量的中微子通量,以期解释PeV中微子事件在冰立方检测到。结果表明,在不久的将来,银河系磁星产生中微子事件的可能性非常低。

英文摘要:

The paper estimates the flux of PeV neutrinos from magnetar polar caps, assuming that ions/protons are injected, and accelerated in these regions and interact with the radiative background. The present study takes into account the effect of the photon splitting mechanisms that should modify the radiative background, and enhance the neutrino flux at PeV energies, with a view to explain the PeV neutrino events detected in IceCube. The results indicate that in near future, a possibility of any significant excess of neutrino events from a magnetar in Milky Way is extremely low.
