论文摘要
银河超新星残留物（SNR）对宇宙射线起源（CRS）的贡献是现代天体物理学中的重要开放问题。宽带非热排放是探测SNR中CRS能源预算和生产历史的有用代理。 We conduct hydrodynamic simulations to model the long-term SNR evolution from explosion all the way to the radiative phase (or $3\times10^5$ yrs at maximum), and compute the time evolution of the broadband non-thermal spectrum to explore its potential applications on constraining the surrounding environments as well as the natures and mass-loss histories of the SNR progenitors.在分为两个主要组的环境环境上进行了参数调查，即具有均匀气体密度的均匀介质，另一个具有由大型红色 - 苏皮形（RSG）祖细胞恒星的恒星风产生的折线结构。我们的结果揭示了非热发射与SNR的环境特征密切相关的高度多样化的进化史。在辐射阶段之前，研究了CR重新加速和离子中性波在光谱进化中的作用。最后，我们通过下一代硬X射线天文台力量对SNR观察的未来前景进行评估，并预测我们可以从与进化模型的比较中学到的东西。
The contribution of galactic supernova remnants (SNRs) to the origin of cosmic rays (CRs) is an important open question in modern astrophysics. Broadband non-thermal emission is a useful proxy for probing the energy budget and production history of CRs in SNRs. We conduct hydrodynamic simulations to model the long-term SNR evolution from explosion all the way to the radiative phase (or $3\times10^5$ yrs at maximum), and compute the time evolution of the broadband non-thermal spectrum to explore its potential applications on constraining the surrounding environments as well as the natures and mass-loss histories of the SNR progenitors. A parametric survey is performed on the ambient environments separated into two main groups, namely a homogeneous medium with a uniform gas density and one with the presence of a circumstellar structure created by the stellar wind of a massive red-supergiant (RSG) progenitor star. Our results reveal a highly diverse evolution history of the non-thermal emission closely correlated to the environmental characteristics of a SNR. Up to the radiative phase, the roles of CR re-acceleration and ion-neutral wave damping on the spectral evolution are investigated. Finally, we make an assessment of the future prospect of SNR observations by the next-generation hard X-ray space observatory FORCE and predict what we can learn from their comparison with our evolution models.
