年轻超新星遗迹的Gamma-ray发射:强子还是轻子?

Gamma-ray emission from young supernova remnants: hadronic or leptonic?

S. Gabici, F. A. Aharonian

摘要:

关于年轻超新星遗迹的伽马射线发射的性质的争论仍然是开放的。将这种辐射归因于强子过程而不是轻子过程,将为质子和原子核的加速提供证据,这一事实将符合非常流行的(但未被证实的)范式,即超新星遗迹是银河系宇宙射线的来源。在这里,我们讨论这个问题,特别关注研究得最好的伽马射线明亮的超新星遗迹:RX~J1713.7-3946。

英文摘要:

The debate on the nature of the gamma-ray emission from young supernova remnants is still open. Ascribing such emission to hadronic rather than leptonic processes would provide an evidence for the acceleration of protons and nuclei, and this fact would fit with the very popular (but not proven) paradigm that supernova remnants are the sources of Galactic cosmic rays. Here, we discuss this issue with a particular focus on the best studied gamma-ray-bright supernova remnant: RX~J1713.7-3946.
