低光度伽马射线暴中最高能量处穿过脚踝的宇宙射线和扩散中微子的共同起源

On the common origin of cosmic rays across the ankle and diffuse neutrinos at the highest energies from low-luminosity Gamma-Ray Bursts

Denise Boncioli, Daniel Biehl, Walter Winter

摘要:

我们证明了低亮度伽马射线暴(LL-GRB)喷流核级联中产生的超高能电子回旋共振(UHECR)可以描述UHECR的谱和成分,同时也可以描述最高能量处的扩散中微子通量。源中的辐射密度同时控制着中微子的产生和核级联的发展,导致核子和轻核的通量,甚至描述了$5 \times 10^{18}$ eV的宇宙线踝。导出的源参数是一致的人口研究,表明重子加载因子约为10。我们的研究结果激发了LL-GRB作为一个独特的GRB人口的持续实验搜索。

英文摘要:

We demonstrate that the UHECRs produced in the nuclear cascade in the jet of Low-Luminosity Gamma-Ray Bursts (LL-GRBs) can describe the UHECR spectrum and composition and, at the same time, the diffuse neutrino flux at the highest energies. The radiation density in the source simultaneously controls the neutrino production and the development of the nuclear cascade, leading to a flux of nucleons and light nuclei describing even the cosmic-ray ankle at $5 \times 10^{18}$ eV. The derived source parameters are consistent with population studies, indicating a baryonic loading factor of about ten. Our results motivate the continued experimental search of LL-GRBs as a unique GRB population.
