摘要:

Blazar强子模型在过去的几十年中被发展成为轻子模型的替代。在强子模型中,伽马射线辐射与质子和/或质子-光子相互作用中产生的次级轻子的同步辐射有关。与光子一起,强子发射模型预测了中微子的发射,因此中微子是耀变体喷流中相对论性强子加速的确凿证据。质子-光子相互作用和所有相关辐射过程的模拟是一项复杂的数值任务,文献中采用了不同的方法来解决这个问题。到目前为止,还没有系统的比较不同的代码已经进行,防止在数值模拟的基本不确定性的清晰理解。为了填补这一空白,我们进行了第一次全面的比较耀变体强子代码,从这方面的努力的结果将在这方面的贡献。

英文摘要:

Blazar hadronic models have been developed in the past decades as an alternative to leptonic ones. In hadronic models the gamma-ray emission is associated with synchrotron emission by protons, and/or secondary leptons produced in proton-photon interactions. Together with photons, hadronic emission models predict the emission of neutrinos that are therefore the smoking gun for acceleration of relativistic hadrons in blazar jets. The simulation of proton-photon interactions and all associated radiative processes is a complex numerical task, and different approaches to the problem have been adopted in the literature. So far, no systematic comparison between the different codes has been performed, preventing a clear understanding of the underlying uncertainties in the numerical simulations. To fill this gap, we have undertaken the first comprehensive comparison of blazar hadronic codes, and the results from this effort will be presented in this contribution.
