论文摘要
2017年在历史上一个安静的状态下观察到低亮度活跃的银河系核M87，Fanaroff-riley I无线电 - 甘马的原型。虽然单独的Leptonic Jet模型无法解释核心无线电与伽马射线射线光谱，我们探索了混合喷气式式喷射式风景。在这项工作中，我们将M87核心的整体光谱能量分布建模，并具有主导的单区Lepto-HADRONIC JET组件，并与增生流的贡献相结合。我们发现近距离设备参数集适用于该参数，该参数适合无线电数据和伽马射线频段，而积分流则主要有助于X射线频段。探测了对地球传播过程中伽马射线吸收的影响，并且发现该模型可以忽略不计。还计算了由这种情况产生的中微子通量，但仍低于当前仪器的敏感性。
The low-luminosity Active Galactic Nuclei M87, archetype of Fanaroff-Riley I radio-galaxies, was observed in a historically quiet state in 2017. While one-zone leptonic jet models alone cannot explain the core radio-to-gamma-ray spectrum, we explore a hybrid jet-disc scenario. In this work, we model the overall spectral energy distribution of M87's core with a dominating one-zone lepto-hadronic jet component, coupled with the contribution from the accretion flow. We find close-to-equipartition parameter sets for which the jet component fits the radio-to-optical data as well as the gamma-ray band, while the accretion flow mainly contributes to the X-ray band. The effects of gamma-ray absorption by the Extragalactic Background Light during the propagation towards Earth are probed and are found to be negligible for this model. The neutrino flux produced by such scenarios is also calculated, but remains below the current instruments' sensitivity.
