论文摘要
模型中有很大的解释，解释了大耀斑。在这里，我们研究了由移动和扩展的斑点引起的耀斑曲线，特别强调了伽马对的生产。我们首先开发了一个简单的半分析模型，以研究扩展斑点中颗粒分布的演变，并显示对生产的影响。在第二步中，我们使用基于PKS 1510-089的参数的onehale代码生成了逼真的仿真。半分析模型表明，这对产生显着影响耀斑的演化，而开头和膨胀可以大大延长耀斑。基于PKS 1510-089的仿真表明，移动膨胀斑点的耀斑导致强烈的波长依赖光曲线，包括延迟的二次耀斑。移动的，扩展的斑点会引起重要的爆发事件，其光曲线轮廓种类繁多。为了得出引起耀斑的细节，需要进行高振动多波伦大小观测。超出初始突发的扩展观测可能会提供有关开头角度和由于某些能带延迟次级耀斑引起的颗粒含量的重要信息。
There is a large variety in the models explaining blazar flares. Here, we study the flare profile induced by a moving and expanding blob with special emphasize on the gamma-gamma pair production. We first develop a simple semi-analytical model to study the evolution of the particle distribution in the expanding blob and show the influence of the pair production. In a second step, we produce a realistic simulation using the OneHaLe code based upon parameters of PKS 1510-089. The semi-analytical model shows that the pair production significantly influences the flare evolution, while the opening angle and the expansion can prolong flares considerably. The simulation based on PKS 1510-089 indicate that flares of a moving expanding blob result in strongly wavelength dependant light curves including delayed, secondary flares. A moving, expanding blob can cause significant flaring events with a large variety in light curve profiles. High-cadence multiwavelength observations are necessary to derive the details causing the flare. Extended observations beyond the initial burst may provide important information on the opening angle and the particle content due to delayed secondary flares in some energy bands.
